The present invention is the series of network access technology solution proposed for the development in response to Internet of Things, applied field Scape is more suitable for the local area network realized with WiFi technology, but theoretically should be with operating system without being necessarily associated with.Based on this, originally Invention not only provides target network on the one hand for the mobile intelligent terminal of the similar mobile phone of central control action etc and connects Enter guidance method and corresponding device, providing automation to access the target network for other smart machines, intelligent terminal connects The guide entered, moreover, on the other hand, or independently of its except the intelligent terminal for playing central control action His smart machine, intelligent terminal provide target network cut-in method, so that the intelligent terminal is improved, to realize such intelligence eventually Exempt from setting access target network in end.In view of this, the following description will be around the expansion description respectively of these aspects.Described connects Enter guidance method and cut-in method, is substantially the different aspect for belonging to a system schema.Utilize the access guiding side Method is dished out the data of guide formula, and the cut-in method can be then utilized, real on the basis of using the guide formula data Existing network insertion.

It is necessary to first carry out following guiding explanation to application scenarios of the invention and its principle.

The present invention wants improved mobile phone terminal, will implement target network access guidance method provided by the invention, accordingly , the present invention wants improved intelligent terminal, will implement target network cut-in method provided by the invention.Mobile phone terminal and intelligence Terminal, which cooperates, completes the operating process that intelligent terminal accesses the target network, and the target network is that mobile phone terminal is current The network of access, intelligent terminal access configuration information required for the target network, are provided by mobile phone terminal.

But for cost or succinct consideration, intelligent terminal is usually the relatively simple equipment of function or even certain feelings Human-computer interaction interface cannot be provided under condition, in this case, cannot allow such as mobile phone user setting WiFi network SSID and Therefore the information such as password in technical principle, need to transmit these configuration informations from mobile phone terminal to intelligent terminal, so as to intelligent end Target network is accessed after end configuration itself.

The mobile phone terminal configuration information described to intelligent terminal transmission, typically can as the present invention will disclosed in implementation Described in example, at least implemented using two ways, first way is the point-to-point direct-connected skill based on WiFi Direct standard implementation Intelligent terminal is placed in the service node mode (ap mode) by the standard criterion by art, waits mobile phone terminal with work station (STA) Its backward transmission of mode entry intelligent terminal configuration information, until intelligent terminal obtains the configuration information, and it will The workstation mode for itself switching back to the standard configures itself and accesses target network, thus completes from confidence Breath is transferred to the overall process of access.This process is all based on the network for working in data link layer that 802.11 agreements are standardized Frame realizes transmission；The second way is described will to match confidence based on acoustic signals carrier transmission technique provided by the invention Breath is integrated in an audio file with music information, plays the audio file, generates acoustic signals, is received simultaneously by intelligent terminal After parsing, configures itself and complete the access of target network.No matter which kind of mode is taken, if the configuration information is without adding It is close, it is just easy to be intercepted and captured and cracked by Malware in transmission process, is all exposed to hacker so as to cause entire target network. Therefore, between intelligent terminal and mobile phone terminal provided by the invention, the characteristics of sufficiently excavating and utilize asymmetric encryption techniques, Both guarantee the communication security of mobile phone terminal and intelligent terminal, and it is expected the more unexpected technical effects of harvest.

Asymmetric encryption techniques, also known as public key cryptography refer to (being disclosed close by corresponding a pair of of unique keys Key and private cipher key) composition encryption method, public-key cryptography is public key, and private cipher key is private key, between public key and private key It is associated with by algorithm uniqueness, realizes association mathematically, the ciphertext via private key encryption can be decrypted using public key, otherwise So.Currently known rivest, shamir, adelman is more, such as RSA, ElGamal, knapsack algorithm, Rabin, Diffie-Hellman (D-H) public key encryption algorithm in Key Exchange Protocol, (ECC, elliptic curve add Elliptic Curve Cryptography Close algorithm) etc..Those skilled in the art should be enough to understand the flexible fortune of this widely applied technology and its various algorithms With.Public key encryption solves the publication and problem of management of key, is the core of current commercial code.In public encryption system, It does not disclose in plain text, discloses ciphertext.

Based on asymmetric encryption techniques, when intelligent terminal of the invention dispatches from the factory, it is written on its chip and is added by asymmetric The private key that secret skill art generates, also, simultaneously, in a manner of being appended hereto hardware, or in a manner of Web Publishing etc., the open and private The associated public key of key.Theoretically, an intelligent terminal holds a pair of of private key and public key, not only may insure using the public key Secure communication is realized with intelligent terminal, and can be used for examining the legitimate origin or channel of intelligent terminal.In view of work On it is practical and convenient, the public key of intelligent terminal is printed on the packing box of intelligent terminal or a visualization table of its shell It is characterized up in region, and with the format of two dimensional code, in this way, mobile phone terminal of the invention utilizes a two-dimensional code scanning mould Block is scanned the two dimensional code of the public key for characterizing intelligent terminal, can obtain the public key.Mobile phone terminal utilizes the public key Encryption configuration information forms ciphertext and is transferred to intelligent terminal, and intelligent terminal has private key by oneself with it and decrypts the ciphertext received, then Configuration information therein is extracted, whole process is safe and reliable.

In the scene of some variations, by the service node mode for the intelligent terminal realized based on WiFi Direct technology Under log-on message and the public key expressed in the two dimensional code together, mobile phone terminal scans the two dimensional code, obtains public While key, corresponding log-on message can be also obtained.After configuring itself using the log-on message, that is, it can access intelligence eventually End, to establish point-to-point direct-connected carry out data transmission.It therefore in this case, can be by mobile phone after one key scanning of user Terminal and intelligent terminal silence cooperate, and realize the intelligent terminal access target network.

In certain scenes, if intelligent terminal is a camera, user wishes that subsequent mobile phone terminal can receive intelligent terminal The video data of offer, and it is desirable that carry out safer encryption to this video data, can be by mobile phone terminal using non- Symmetric cryptosystem generates a pair of new key, and mobile phone terminal retains own private key, its public key is transferred to intelligent terminal, intelligence Its data to be transmitted can be transferred to mobile phone terminal using the public key encryption by terminal, and mobile phone terminal has private key solution by oneself with it Close acquisition video data gives that expression display can be perceived.Certainly, this Technology application can increase the operation load of mobile phone terminal, but It is effective.Although asymmetric techniques safety with higher, intelligent terminal once factory, private key with Public key has been fixed, immutable, and once for a long time, be still cracked possibility, therefore, in the field that high security requires, is passed through The new key that mobile phone terminal generates ensures the secure communication between mobile phone terminal and intelligent terminal, has positive effect.

It will be detailed below several skills of the invention proposed to realize above-mentioned scene with above-mentioned principle The specific embodiment of art scheme.

It should be noted that a kind of target network provided by the invention accesses guidance method, be as active initiator, or What person was described as the visual angle of central controlling party, which can be embodied as by computer program by programming and existed Similar mobile phone terminal, tablet computer or have in intelligentized control equipment is run, for example, run Android, IOS, The mobile phone of Windows Phone system or the APP (application program) that guidance method realization is utilized with installation in tablet computer, by The application program executes the guidance method.

Referring to Fig. 1, this method is specifically wrapped in an exemplary embodiments of target network access guidance method of the invention Include following steps:

Step S11, two-dimensional code scanning user interface is called to obtain the public key of intelligent terminal.

As in the preceding description in relation to scene, intelligent terminal provides corresponding in such a way that two dimensional code carries out Visualization Public key, mobile phone terminal activate two-dimensional code scanning functional module, wait user's by the user interface of its two-dimensional code scanning of calling Scan operation.After two dimensional code of the mobile phone terminal to nearly intelligent terminal is expressed region by user, the public key of intelligent terminal can be obtained.

If it is made itself to be under service node (AP) mode by intelligent terminal based on what WiFi Direct technology was realized Service set (SSID), the password even log-on messages such as cipher mode and the public key characterize together in its two dimension At code, this step can naturally also obtain the log-on message while obtaining the public key, in later use.

Step S12, ciphertext is formed using the configuration information of public key encryption access current goal network.

It is well known that not only having WiFi mould group, display, control chip on mobile phone, also there is microphone, loudspeaker Equal components, these components can be implemented to call by the APP installed on mobile phone terminal, correspondingly, guidance method of the invention Executing subject is the mobile phone for being loaded with the APP specially realized.

Due to the main object of the present invention be in order to handle network access technique, the target network being currently accessed, just Refer to network representated by WiFi AP that mobile phone is just accessing at present, and the configuration information, it is also to access the target network Required login authentication information.According to the agreement of WiFi agreement, those skilled in the art be could be aware that, these information generally include The service set (SSID) and login password of WiFi wireless routing (representing target network), also need in some cases include The cipher mode of login password, and login password can also be needed not be provided for open network.Although there are versions for WiFi agreement more For the fact, but these be related to realize access network and indispensability configuration information can by those skilled in the art according to agreement text Part is corresponding to be determined, therefore, is repeated here to its details and its change programme.

When mobile phone terminal itself accesses target network, by the Beacon frame of scanning WiFi AP, or pass through transmission Probe Request frame provides modes such as the response frame Probe Response that obtains WiFi AP, or with user in APP Interface on active setting match, to determine a service set, i.e. SSID determines that one to be accessed with this WiFi AP network is also that a target network to be accessed has been determined.Then, mobile phone terminal will usually be obtained to user with The corresponding login password of the SSID (except open network), corresponding cipher mode such as WPA, WPA2, WEP and its details Deng, can both have been selected by user and also by mobile phone terminal by its WiFi mode realize automatic identification.After obtaining these basic informations, By a series of conventional association (Association) operation, mobile phone terminal can be accessed to the target network, as a result, hand Configuration information needed for machine terminal also just obtains access target network.These configuration informations were both potentially stored in the machine, It can be only stored in running memory, depending on default option of the user when network insertion option is arranged.In general, can lead to The configuration file about network insertion of lookup the machine is crossed to recognize its archive to the configuration information of network.It is real in certain applications In example, also can provide a series of interfaces obtain user to service set scan select and its corresponding password, from And determine corresponding configuration information.

Once obtaining the configuration information, it can be encrypted using well known asymmetric encryption techniques, be encrypted Content afterwards forms ciphertext, which needs to decrypt using the own private key of intelligent terminal, correctly to obtain wherein Configuration information.

If, can be by mobile phone end as previously described for the communication security reinforced between subsequent mobile phone terminal and intelligent terminal End generates a pair of of new key using asymmetric encryption techniques, and mobile phone terminal stores its own key, and its public key is appended hereto institute The configuration information stated encrypts form ciphertext together, awaiting transmission.

Step S13, pass through ciphertext described in radio signal propagation.

The ciphertext constitutes a kind of guide formula data, is propagated by wireless signal, receives this ciphertext Intelligent terminal can realize logic, the information for being included using the ciphertext, to realize access target network according to intrinsic program The purpose of network.

The circulation way of ciphertext, the realization dependent on the communication link between mobile phone terminal and intelligent terminal.Before such as The scene and its flexible situation of change, it will be understood that, can be at least using two kinds of thinkings of WiFi standard and acoustic signals as axis Develop out following several implementations:

It is described close to transmit that one, the public key for obtaining intelligent terminal simultaneously and log-on message silence establish communication link Text.

The case where log-on message of itself is published on its two dimensional code suitable for intelligent terminal, the present invention are calling two dimensional code When scanning user interface is scanned two dimensional code, i.e., the public key of intelligent terminal is obtained simultaneously and is logged in needed for intelligent terminal Log-on message.Mobile phone terminal disconnects the connection with target network, after configuring itself using the log-on message, that is, can access positive place Intelligent terminal under service node mode, to establish point-to-point communication link.Then, can 802.11 agreements number According to the format of the data frame of the link layer ciphertext described to intelligent terminal transmission.Intelligent terminal receive corresponding wireless signal it Afterwards, utilization is decrypted to it.After waiting intelligent terminal completion configuration information reception, voluntarily it is switched to workstation mode and attempts access When target network, the communication link of mobile phone terminal and intelligent terminal is disconnected, and just can be self-healing mobile phone terminal and target network Connection.The realization of this process does not depart from a kind of convenience fortune of the technical foundation such as WiFi Direct or AD-Hoc actually With, a key operation may be implemented, those skilled in the art should know.

Secondly, according to predetermined protocol scanning discovery and establish with the communication link of intelligent terminal to transmit ciphertext.

By the point-to-point communication technology of WiFi Direct or Ad-Hoc etc, according to the protocol rule of default, by holding Hand and connective methods are built between the mobile phone terminal for being loaded with APP of the present invention and one or more external smart machine Vertical communication link, or only detect the ciphertext hiding in (such as Probe Request) in one or more detection, with The form of WiFi signal radiates in space and realizes broadcast.Refering to aforementioned, in some typical examples, it is based on WiFi Direct skill Art, intelligent terminal default are in AP operating mode, and waiting mobile phone terminal is shaken hands and is associated with STA mode, connect to realize Enter, the ciphertext that mobile phone terminal can be described to intelligent terminal transmission by data frame in the case where access.But if intelligence There is improved rendezvous protocol rule between terminal and mobile phone terminal, then only need a side to load on ciphertext one or more In a detection frame or in other management frames or control frame, another party also can get ciphertext (such case that these frames are included Under, the connection status that can really transmit data frame is not implemented in mobile phone terminal and intelligent terminal).Intelligent terminal is either with even The mode of state is connect, or after receiving configuration information in a manner of notconnect state, then switch back into STA mode, described in access Target network.

It can be seen that can use a variety of based on the existing various technological visions of WiFi and its neighboring technology specification Improved means realize the foundation of the communication link between mobile phone terminal and intelligent terminal, and the ciphertext is passed through Including control frame, management frame, data frame it is various using 802.11 agreements as standard network frame formed wireless signal into Row transmission.

Thirdly, non-under the WiFi connection status, the ciphertext that utilizes acoustic signals broadcast described.

In one embodiment, three frequency frequency meters are set, 3 frequency signals are generated to edition data.By the version number of 16 systems 3 are divided into multiple groups of data for one group accordingly, select corresponding frequency synthesis 3 to believe frequently in three frequency frequency meters according to sequencing Number.

3 frequency signals are respectively as follows:

0.3*sin(2.0*M_PI*threefTable[0][num1]*i*T)、

0.3*sin(2.0*M_PI*threefTable[1][num2]*i*T)、

0.4*sin(2.0*M_PI*threefTable[2][num3]*i*T))；

5 are located at the third place, then choose frequency fTable [2] [5] and coefficient on the 6th position of third group frequency sigcoeff[1]。

The rest may be inferred, generates corresponding signal respectively and is added again, i.e.,

sigcoeff[0]*sin(2.0*M_PI*fTable[0][7]*i*T)+

sigcoeff[1]*sin(2.0*M_PI*fTable[1][6]*i*T)+

sigcoeff[2]*sin(2.0*M_PI*fTable[2][5]*i*T)+

sigcoeff[3]*sin(2.0*M_PI*fTable[3][4]*i*T)+

sigcoeff[4]*sin(2.0*M_PI*fTable[4][3]*i*T)+

sigcoeff[5]*sin(2.0*M_PI*fTable[5][2]*i*T)+

sigcoeff[6]*sin(2.0*M_PI*fTable[6][1]*i*T)+

sigcoeff[7]*sin(2.0*M_PI*fTable[7][0]*i*T)。

0=< i < NFRAME, NFRAME are frame length, this signal just contains 76543210 this 8 in same amount of time Data information.The bandwidth of 8 groups of frequencies in fTable does not overlap.

As it can be seen that through the above steps, the conventional coding means that can flexibly use in conjunction with those skilled in the art are same, just The coding to the configuration information can be achieved, " modulation " arrives some specific frequency of sound wave in the form of digitized by configuration information On, it is configured to the audio-frequency information for broadcasting, is associated in specific one or multiple sound channels.

Step S132, preset music score of Chinese operas file is read, is based on the music score of Chinese operas file generated music information, and by the music Information coding is not filled by one or more sound channels of audio-frequency information into multichannel.

Similarly by taking Dolby Digital multi-channel system as an example, if the coded audio information into L channel, The music information can be encoded in right channel.It is well known that since Dolby Digital ambiophonic system is by 5 Full frequency-domain sound channel and 1 subwoofer sound channel composition, also referred to as 5.1 sound channels, 5 sound channels be respectively it is left front, right before, it is preceding in set, it is left It surrounds and right surrounds, music signal and audio-frequency information can actually be filled into respectively to one or more sound of this 5 sound channels In road, a sound channel is respectively accounted for each other without limiting to.

Specifically, realizing that the process of coding is referred to following specific steps and realizes using music score of Chinese operas file:

Step a, circulation read music score of Chinese operas file.

Step b obtains the number for representing numbered musical notation.

Step c obtains the symbol for representing tone.

Step d obtains the symbol for representing beat.

Step e calculates the duration of each sound.

Step f, gives out music signal.

Step g, is filled into right channel.

The music score of Chinese operas file follows certain agreement or rule and realizes, can be realized using currently known music score of Chinese operas file Form can also use some existing melodies, can both be provided by system default, can also be supplied to user and carry out customized set Its source or music score of Chinese operas coding are set, as long as method of the invention is corresponded to parsing according to the agreement or rule.Such as:

In one embodiment, music score of Chinese operas file can represent the letter of " tremble, thunder, miaow, send out, search, drawing, is uncommon " using number 1-7 Spectrum, symbol+,-,=etc. respectively represent in high C tune C and reconcile the tones such as low C tune, symbol！,@, #, $, %, * respectively represent entirely Bat, 1/2 bat, 1/4 bat, 1/8 bat, 1/16 bat, 3/2 bat and 2 bats.

Per minute 60 are defined to clap, i.e., one to clap be 1 second, the frequency of high C tune be 1047,1175,1319,1397,1568, 1760,1976}；The frequency of middle C tune is { 523,587,659,698,784,880,988 }；The frequency of low C tune be 262,294, 330,349,392,440,494}；Unit is Hz.

3 are one group in music score of Chinese operas file, represent a sound, such as 6=！Indicate " drawing " sound for the low C tune clapped entirely, i.e. frequency For 440Hz, the time is 1 second, and the signal calculation formula of this sound is 0.8*sin (2.0*M_PI*f*j*T) * w [j]；0=< j < Wherein f selects 440Hz, ptichTime to select 1 second to pitchTime, and w [j] is window function.Every 3 are recycled as one group of reading Music score of Chinese operas file generates corresponding syllable and is combined into music.

As can be seen that using above-mentioned process, corresponding music information can be generated using music score of Chinese operas file, those music letter Breath is encoded into one or more sound channels different from the audio-frequency information position of multi-channel system, establishes sound channel Being associated between music information.

Step S133, the coded data comprising the audio-frequency information and the sound channel of music information is converted into specific format Audio file.

After the coding of the coding and music information that complete above-mentioned audio-frequency information, corresponding coded number is just formd According on this basis, the coding of each sound channel being independently converted into the monophone of specific format with well known mode Audio file or the multitrack audio file for being integrally converted into specific format are completed audio-frequency information and music information The operation of Composite tone file.As for the format of audio file, more flexibly, such as audio file formats known in wav, mp3 etc. It can realize this conversion, by related crossover tool without enumerating.

This audio file realized, substantially by the close of the configuration information comprising access target network Text is loaded into music information in a manner of digitized, therefore, by playing these audio files, can be carried out by sound wave Data broadcasting.

Then, after generating the audio file, that is, corresponding playout software is called to play the audio file, to form sound wave Signal is propagated in free space, to broadcast the ciphertext comprising configuration information.

The mobile terminal of mobile phone etc, generally be configured with corresponding audio playing software, due to audio file be according to What specific format was converted, it can normally be identified by audio playing software, therefore, by calling audio playing software, Play the audio file.As previously mentioned, audio file can be the audio-frequency information comprising configuration information and the sound Two files that happy information is separately encoded, can also be integrated into same file, regardless of its way of realization, can lead to here It crosses music player software to carry out while playing, the music information described in broadcasting while playing audio-frequency information, from there through raising The music that sound device plays back weakens the broadcast effect of the audio-frequency information.Data are formed by playing audio-frequency information Music is played while sound wave, is allowed the sound of broadcasting not seem dull, is improved the audio experience for playing sound, played data sound wave While play music, song, the sound such as voice, improve the rhythmical image and timing for playing sound, improve and play listening for sound Feel impression, and influence is transmitted without on data.Audience is capable of the music of hearing devices sending, also just can clearly know to lead to Letter process realizes better man-machine interaction experience.

It is in order to which data sound wave caused by audio-frequency information is hidden in institute it should be pointed out that carrying out multichannel broadcasting Within the scope of the playing duration for stating music caused by music score of Chinese operas file, musical sound is enabled to weaken data sound wave, as long as abiding by Such substantially rule is kept, just need not emphasize the tight consistent of the broadcasting initial time of each sound channel.Also, in general, each sound The broadcasting initial time in road, theoretically also uses restraint in coding stage, and therefore, those skilled in the art protect the present invention The understanding of shield range should not be bound to this one can flexible technical characteristic.

By playing the audio file, data broadcasting effect is realized, so that the configuration information comprising target network Ciphertext in the form of the appreciable acoustic signals of human ear (20Hz~20KHz) to airborne spread, in general interior space model It in enclosing, can be received by corresponding radio equipment, to realize that data are transmitted.In the acoustic signals formed according to this form In, since the ciphertext comprising configuration information is converted according to specific frequency point, just described to be formed by ciphertext Transmission data are loaded into music sound wave signal in a manner of carrier wave, by related communication processing means, can be extracted wherein Ciphertext be used.

The process of data is received the decode and extracted about to by playing the audio file, will be sent out at subsequent It is further disclosed in bright target network cut-in method.

As can be seen that the embodiment of the disclosure above, it is sufficient to mobile phone terminal be made reliably to contain target network to spatial The ciphertext of the configuration information of network, as long as various wireless signals enumerated above can be received and parsed to it, and solution Close ciphertext therein finally obtains configuration information, theoretically, i.e., the target network described using configuration information access.

In addition, the general improvement project as above-described embodiment, describes please continue to refer to embodiment below, with deeper Enter to understand the present invention.

Referring to Fig. 3, in another embodiment of target network of the present invention access guidance method, it is further provided after following Continuous step:

Step S14, the result information fed back based on the configuration information for being originated from the intelligent terminal is obtained.

The mobile phone terminal of Central Control Function is played, is suitable for that can to know whether intelligent terminal can be successfully accessed in time described Network, and can know this message, then need with necessary identification.Therefore, mobile phone terminal, which will acquire, is originated from intelligence eventually The result information at end, and subsequent processing is made based on this result information.

Intelligent terminal of the invention obtain include configuration information the wireless signal of ciphertext after, it will be parsed and will be utilized Own private key decrypts it, final to obtain the configuration information.In turn, intelligent terminal utilizes the configuration information, obtains related The information such as service set, the password even cipher mode of target network, configure itself, the program of starting access target network, Attempt to establish with target network and be associated with (Association), until establishing connection.Finally, based on this connection attempt as a result, Whether successful result information is for example with several UDP message packet broadcasts (since udp protocol is opposite by characterization connection for intelligent terminal It is unstable, therefore be suitable for once sending multiple data packets), it is sent to mobile phone terminal, in the form of ACK control frame for another example to complete Interactive process.It should be noted that the data that intelligent terminal of the invention issues it will encrypt.Therefore, always Mobile phone terminal in waiting state either by network frame, or passes through the forms such as UDP message packet or even sound carrier After obtaining the response from intelligent terminal, all it is regarded as result information and is subject to subsequent processing.

Result information described in step 15, the public key decryptions using the intelligent terminal.

After no matter mobile phone terminal obtains the result information from intelligent terminal in what manner, the intelligent terminal is just utilized Public key trial this result information is decrypted.The success or failure of decryption will affect mobile phone terminal to the legal next of intelligent terminal The judgement in source.It similarly, can also be to being considered as intelligent end if intelligent terminal fails to receive the result information from intelligent terminal always End fails to decrypt the information with the public key encryption, to make certain judgement.It should be noted that result letter designated herein Breath, unrelated with the content that it is characterized, which has accessed target network either characterizing intelligent terminal, can also be with table Sign intelligent terminal, which fails, accesses target network.Mobile phone terminal only focuses on here using asymmetric techniques and realizes product Identification.

If step 16 determines --- it fails to decrypt to fail in the result information or scheduled duration and obtain When taking the result information, warning information is generated.

As previously mentioned, the public key for the intelligent terminal that mobile phone terminal obtains, should be theoretically the private key phase with intelligent terminal Match, otherwise, may infer that intelligent terminal is fake products, or although can not conclude that intelligent terminal is fake products, until The public key being provided by it less has been tampered with.No matter which kind of situation, all have reason to mention the legitimate origin of the product or its channel Query out.Specifically, mobile phone terminal fails when decrypting the result information, it was demonstrated that the private key of intelligent terminal is provided with it Public key be not same to mathematically associated password pair；Mobile phone terminal fails when obtaining the result information, also pole It is possible that because intelligent terminal cannot be decrypted correctly mobile phone terminal and no result information is caused to ring using the data of the public key encryption It answers, therefore also turns out that the private key of intelligent terminal with its public key provided is not same to mathematically associated password pair.This feelings Under condition, mobile phone terminal can be by user interface display alarm message, or by loudspeaker sonorous alarm etc., generates alarm letter Breath.Further, if equipped with the technology alerted when cannot decrypt the ciphertext from mobile phone terminal when it in intelligent terminal Means, then user can more clearly determine whether that this identity is tested with the respective warning information of intelligent terminal by mobile phone terminal Card process receives the influence of signal of communication stability, to be conducive to exclude necessary interference, Accurate Diagnosis leads to intelligent terminal The problem of target network can not be accessed.

As it can be seen that the embodiment of above-mentioned extension, further the advantages of performance asymmetric encryption techniques, determines intelligence eventually for user The legal identity at end and for user check connectivity problem provide convenient and fast technical foundation.

It should be pointed out that in some scenes above-mentioned, it is indicated that in some cases, mobile phone terminal is transmitted to intelligent terminal When configuration information, the public key for the password centering that it is voluntarily generated also is transmitted to intelligent terminal, is safer for the ease of ensuring Data laser propagation effect.In these scenes, mobile phone terminal can be connect it for computational efficiency and communication security consideration is improved The data from the intelligent terminal received, only when can be with the private key successful decryption for the password centering that mobile phone terminal voluntarily generates When, the progress of these data just can be perceived into expression processing, express that it with audio, video, picture and text, the sound and other effects, be User is perceived.

It can be seen that target network of the invention accesses guidance method, realizes safer reliably propagate and access mesh The method for marking the configuration information of network, can more effectively guide external smart terminal and more safely access in target network.

In intelligent terminal side, due to needing the foundation between the mobile phone terminal for sending the ciphertext comprising configuration information corresponding Property, therefore, it is possible to be realized by target network cut-in method of the invention.

Referring to Fig. 4, target network cut-in method of the invention includes the following steps:

Step S21, external wireless signals are read to be parsed, obtains wherein entrained ciphertext.

In the access guidance method that aforementioned related mobile phone terminal is realized, give a variety of for propagating the nothing of the ciphertext Line signal form, preferred two kinds of wireless signals, one is the work realized based on WiFi technology data link layer network Frame, another kind is can acoustic signals characterized by auditory frequency range by human ear.And in former wireless signal, then it can be flexible (such as management frame, data frame) is propagated on ground with different types of network frame, depends on those skilled in the art how clever completely R. concomitans WiFi Direct standard and Ad-Hoc standard living.And latter wireless signal, then it needs with corresponding decoding technique To obtain the ciphertext that acoustic signals are included.Anyway, data are obtained from wireless signal, are that number is loaded in wireless signal According to inverse process, the embodiment stated before this invention provides full and accurately to be realized and loads data into skill in wireless signal On the basis of art scheme, it will be appreciated by those skilled in the art that even if the description subsequently with respect to each embodiment can not be detailed, it can also Voluntarily the loading technique according to aforementioned announcement knows subsequent corresponding scheme, that is, using mobile phone terminal realization come certainty The realization of ground acquisition intelligent terminal.It is provided nevertheless, those skilled in the art still can refer to several times for several different situations Related acquisition ciphertext explanation it is of the invention to understand:

One is directed to the case where transmitting ciphertext based on 802.11 agreements (WiFi technology):

No matter which kind of mode intelligent terminal is accessed using in the aforementioned guidance method implemented in relation to mobile phone terminal, works as the two When based on establishing point-to-point direct-connected relationship, data frame transfer data can be passed through；Even if the two fails to establish point-to-point direct-connected pass System can also realize that data are transmitted, therefore, whether based on WiFi Direct by the frame format of control frame, management frame etc Technology is still based on Ad-Hoc technology, in spite of point-to-point notional direct-connected relationship is established, can pass through various forms With 802.11 protocol formats expression work the network frame of data link layer come realize mobile phone terminal to intelligent terminal transmit It carries and contains the purpose of the ciphertext of target network configuration information.Correspondingly, intelligent terminal can be according to WiFi The technical specifications such as Direct, Ad-Hoc, to its received wireless signal carry out the parsing of correspondence, therefrom obtain described close Text.Obviously, it to be farthest compatible with prior art standard, and realizes in an optimal manner, as an exemplary embodiments, Intelligent terminal is suitable for being switched to itself, or default is in service node (AP) mode of WiFi Direct standard, The ciphertext sent is corresponded to according to respective protocol with the mobile phone terminal outside receiving.Configuration in intelligent terminal later use ciphertext Information configuration from behind, then by the workstation mode for itself switching back into WiFi Direct standard so as to complete access mesh Mark the movement of network.

Secondly, for based on acoustic signals transmission ciphertext the case where:

As previously mentioned, mobile phone terminal is by digitized processing, the ciphertext for containing configuration information is special with one or more The form for determining the carrier wave of frequency point is loaded into formation audio file in melody and plays out, and when its broadcasting, that is, is formed and contains carrier wave The wireless acoustic signals of signal, the ciphertext are to load on the load of at least one specific frequency point of airborne acoustic signals In wave.Therefore, the premise for obtaining the ciphertext in acoustic signals is parsed to acoustic signals, and number is converted analog signals into Change data to be handled.

In view of the correspondence of intelligent terminal and mobile phone terminal, corresponding microphone circuit should be arranged to receive in intelligent terminal Via the acoustic signals of spatial.Nature should have accordingly it is also to be understood that in hardware realization to the received sound of institute Wave signal carries out the respective chip that based on simulation or based on number mode is decoded.Theoretically, audio is received For circuit, can not understand whether be music and multichannel, therefore, it is necessary to carry out technical identification.Carry out technology identification Mode is varied, and the following two ways that provides is for those skilled in the art's reference:

First way is the mode based on analog filtering processing:

Intelligent terminal passes through the acoustic signals that its radio reception circuit obtains, and source is varied, only above-mentioned by the present invention The acoustic signals from mobile phone terminal for being loaded with ciphertext, which are only, really needs processed object.And the sound propagated in the sky Wave signal carries out in an analog manner, therefore, can be according to shown in fig. 5 as under type extraction contains configuration information Ciphertext:

Step a, according to given frequency, acoustic signals are filtered, obtain corresponding carrier signal.

The received acoustic signals of institute include multiple carrier waves, the carrier wave therein contained where the ciphertext of configuration information, root Either one or more according to aforementioned, therefore, intelligent terminal (can correspond to aforementioned guiding according to scheduled frequency Frequency listed by the frequency configuration file of method) acoustic signals are filtered, corresponding carrier signal is obtained, the carrier signal It just include the relevant content of the ciphertext.

Step b, digitized sampling is carried out to the carrier signal, obtains corresponding digitalized data.

Because the acoustic signals are substantially analog signals, it is necessarily required in radio reception circuit to filtered Carrier signal carries out analog-to-digital conversion, to obtain the data comprising ciphertext of number.

Step c, the digitalized data is decoded, obtains the configuration information comprising access target network Ciphertext.

Decoding designated herein, because it is only necessary to the digitalized datas to filtered carrier signal to be decoded, because This will become more simple, and those skilled in the art provide according to cataloged procedure above-mentioned in conjunction with latter technique identification method Reference, can realize and decode according to its inverse process, the final ciphertext for containing configuration information accordingly that obtains is for rear continued access Enter target network.

The second way is the processing mode of pure digi-tal.

Since digit chip is widely used in most intelligent terminals, in this case, radio reception circuit has received from the air After the carrier signal, then advanced row digital-to-analogue conversion carries out subsequent processing to the data after conversion.Corresponding processing side Formula has correspondence with cataloged procedure above-mentioned certainly, following to disclose corresponding step for those skilled in the art referring to understanding:

Following detailed step is taken in order to realize the purpose firstly the need of synchronous alignment decoding data head:

Step A1 saves continuous 3 frame audio.Data head is two 16 system numbers.

Step A2 calculates the frequency that intermediate frame includes.

Step A3 calculates the corresponding number of frequency.

Step A4 judges whether number is data head, if it is, entering step 405.

3 frame audio molecule frames are calculated the corresponding number of each subframe by step A5.

Step A6, if the corresponding number of at least continuous 4 subframes is equal to data head.

Step A7, decoding data head.

Step A8, copy remaining data are used for decoding data head, and remaining data have synchronized alignment.

In one embodiment, the audio frame for obtaining load change data detects each audio using goertzel algorithm Multiple frequencies that frame includes, and save loudness of a sound energy corresponding with multiple frequencies；It can be obtained using Goertzel rudimentary algorithm Frequency real and imaginary parts identical with conventional discrete Fou-rier transformation (DFT) or FFT.According to loudness of a sound energy from high to low suitable Sequence calculates the data that each frequency includes in multiple frequencies and carries out RS decoding, and is converted back according to interleaving rule when encoding Original sequence；When judging that error-detecging code is correct, then it is judged as transmission data.

Secondly, needing decoded version number and data length.Specifically include following sub-step:

Step B1 obtains the audio frame for being loaded with version number and data length.

Step B2 detects the frequency that every frame includes using goertzel algorithm.

Step B3 calculates the corresponding data of each frequency.

Step B4 carries out rs decoding when data are 6 full.The algorithm that data number and the RS coding that this step obtains use Correlation, such as RS (7,3) etc..

Step B5, error-detecging code create-rule when according to coding calculate error-detecging code.

Step B6, B7 judges whether version number matches and whether the error-detecging code received is correct, if it is, into Step B8: data length successfully decoded starts decoding data.

Finally, decoding includes the data of ciphertext.It sees below:

Step C1 obtains the audio frame of transmission data.

Step C2 detects the frequency that every frame most probable includes using goertzel algorithm, while saving next may include Frequency, and save the ratio of corresponding energy.

Step C3 calculates the data that most probable includes and the data that next may include according to frequency.

Step C4, interleaving rule when according to coding transform the data into back correct sequence.

Step C5, each section is all first done rs decoding with the data that most probable includes.

Step C6 judges whether every section of error-detecging code is correct, if yes then enter step C8, judges that last error-detecging code is It is no correct.If it is not, then entering step C7, most probable on corresponding position is successively replaced according to the sequence of energy ratio from big to small The data for including are the data that next may include, and make RS decoding.

Step C9 successively judges whether every section of error-detecging code is correct after replacement, if yes then enter step C8, if otherwise It enters step C11: realigning and find data head.

By executing above-mentioned step, corresponding transmission data can be finally obtained, also can be obtained described contain The ciphertext of configuration information.

According to the above-mentioned announcement to two embodiments for obtaining the ciphertext comprising configuration information, could be aware that, intelligent terminal Obtain that mobile phone sends contains the ciphertext of configuration information, therefore, can execute subsequent step.

The ciphertext is decrypted in the pre-stored private key of step 22, reading, obtains configuration information wherein included.

As previously mentioned, the password of intelligent terminal to be it is just generated when leaving the factory, in its production process, password centering Private key be written into corresponding chip, therefore, intelligent terminal can read this pre-stored own private key, and use The ciphertext obtained is decrypted in corresponding asymmetric encryption techniques algorithm, and decrypting resulting data is to be used to access mesh Mark the configuration information of network.It should be noted that between algorithm used in algorithm used in mobile phone terminal and intelligent terminal It is inevitable consistent.Due to the data using private key decryption public key encryption, or otherwise utilize the data of public key decryptions private key encryption Technology is well known to those skilled in the art, therefore without repeating.

In variants of the invention, to determine improper communication convenient for user, when using the private key to the ciphertext progress After decryption failure, the components such as driving sound, light are issued the first warning information by intelligent terminal, and user thus can be true from intelligent terminal Know that the held public key of mobile phone terminal is illegal.It on the other hand, can also be with this case where private key for attempting Brute Force intelligent terminal Kind mode is identified.

In another variants, it is unsuccessfully derived from data transmission quality bad the case where causing in order to exclude private key decryption, intelligence Terminal will utilize one result information of its private key encryption, and by the result information with control frame or data frame even acoustic signals it The form of class feeds back to mobile phone terminal and does corresponding identification, if mobile phone terminal can utilize the public key decryptions result information, two-phase In conjunction with that can know that communication quality is bad, if mobile phone terminal is also warned, in conjunction with warning for intelligent terminal, then mobile phone end can determine Held public key and the held private key of intelligent terminal is held to mismatch.

Corresponding to the variants that mobile phone terminal is realized, when also accompanying includes voluntarily to be generated by mobile phone terminal in the ciphertext Public key when, the present invention will also read the public key, after subsequent intelligent terminal access target network, will utilize the outside public key encryption Data are transferred to the mobile phone terminal as public key provider, and using the public key decryptions mobile phone terminal transmit come data. Due to the variable-key that mobile phone terminal voluntarily generates, it has been cured different from the key of intelligent terminal, so, utilize new public key Communicating with private key will become safer.

Step 23 configures itself using the configuration information and accesses the target network.

After intelligent terminal obtains the configuration information of decryption in the manner previously described, corresponding SSID, password can be obtained very To its cipher mode, then ensuring itself to be under workstation mode, accessed using the WiFi of these information configurations itself Setting starts linker, final to establish the connection for arriving the target network.

In the case of certain, in order to realize more preferably human-computer interaction, refering to described previously, whether intelligent terminal can will succeed The consequential signal of the access target network, with WiFi signal (network frames of 802.11 agreements), Bluetooth signal, acoustic signals Forms such as (similarly with guidance methods of the invention) are back to the source for sending configuration information.A more easy implementation It is that the alarm signal of light and/or sound is carried out by the LED light or the Alarm Unit of buzzer etc that are mounted on this intelligent terminal Confirmation forms the second warning information.Wherein, this notice is realized by Alarm Unit, primarily to human perception is looked after, And by sending consequential signal, then the communication of intelligent terminal and mobile phone terminal can be achieved, understood and carried out such as by mobile phone terminal The preceding utilization, without repeating.It still needs to emphasize, the delivering path of consequential signal is varied, but has succeeded for characterization It accesses for the consequential signal of target network, is suitable for broadcasting the data packets of several UDP formats to notify mobile phone terminal, so as to hand Machine terminal handles subsequent matters as previously described accordingly.And after logging in target network failure with the configuration information, such as Preceding described, intelligent terminal can be used as consequential signal by 802.11 agreements in data link layer or the broadcast table in the form of acoustic signals Sign logs in the network frame of the target network failure.

It needs to be illustrated, the public key of the intelligent terminal when leaving the factory, can be attached directly to the shell of intelligent terminal On one Visualization region of body defined, it is especially on the Visualization region with text or recognizable figure Two dimensional code expresses the public key, subject to machine recognition.Currently, the packaging dispatched from the factory together with intelligent terminal can also be printed on On box or gummed paper, carrier of the gummed paper as two dimensional code, also be may be affixed on the shell of intelligent terminal when necessary.

In addition, corresponding to a variants of aforementioned announcement, with quick response code form come when expressing public key, due to the number of two dimensional code It is larger according to amount of storage, therefore, log-on message when intelligent terminal being under the service node mode of WiFi Direct standard, It can also be contained in together in content expressed by the two dimensional code, so that mobile phone terminal need to only scan the two dimensional code, can obtain simultaneously The public key and log-on message for obtaining intelligent terminal make mobile phone terminal be successfully accessed intelligent end with the log-on message configurating mobile terminal End.

It could be aware that intelligent terminal only needs by the target network cut-in method for being implemented in intelligent terminal disclosed above Reception includes that a series of processing can be completed in the wireless signal for the ciphertext of configuration information for accessing target network, it is not necessary to artificial Intervene, moreover, the communication technology based on safety and extraneous progress data interchange, whole process are apparently more safe and simple, high Effect.
