Description

A wireless local area network authentication method and device

technical field

The present invention relates to the field of communication technologies, and in particular, to a wireless local area network authentication method and device.

Background technique

With the development of wireless technology, the distribution of wireless local area networks is becoming more and more extensive, and user terminals can be connected to the wireless local area network in most places. For example, the user terminal may be connected to a wireless local area network set in a home or company.

In the process of connecting to the wireless local area network, the user terminal needs to perform wireless local area network authentication. By sending a verification message to the gateway of the wireless local area network, the gateway is verified, and the user terminal can be connected to the wireless local area network after the verification is successful. In order to prevent irrelevant user terminals from connecting to the wireless local area network, the wireless local area network often has an authentication code, which requires the user to input the authentication code at the user terminal, and the user terminal includes the authentication code input by the user in the authentication message and sends it to the gateway. This requires the user terminal to have an input function. For example, a user terminal without an input function such as a camera and some smart home appliances requires an external input device on the user terminal without an input function. The user terminal is connected to the gateway. By entering the verification code on the computer, the user terminal without input function such as a camera or smart home appliance sends an authentication message to the gateway, and the gateway performs the authentication. A user terminal without an input function needs to connect an external input device, and by performing an input operation on the external input device, the user terminal without an input function can access the wireless local area network. The process of accessing a wireless local area network by a user terminal without an input function is relatively complicated.

Detailed ways

Features and exemplary embodiments of various aspects of the invention are described in detail below. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, it will be apparent to one skilled in the art that the present invention may be practiced without some of these specific details. The following description of the embodiments is only intended to provide a better understanding of the present invention by illustrating examples of the invention. The present invention is in no way limited to any specific configurations and algorithms set forth below, but covers any modification, substitution and improvement of elements, components and algorithms without departing from the spirit of the invention. In the drawings and the following description, well-known structures and techniques have not been shown in order to avoid unnecessarily obscuring the present invention.

FIG. 1 is an application scenario diagram of a wireless local area network authentication method according to an embodiment of the present invention. As shown in FIG. 1 , the wireless local area network authentication apparatus may be a gateway body connected with an input device and an output device. For example, if a telephone is connected to the main body of the gateway, the microphone of the telephone can be used as an input device, and the receiver or external speaker of the telephone can be used as an output device. The keys of the telephone can also be used as input devices. The phone can be a landline or a mobile phone. In other embodiments, the wireless local area network authentication apparatus may also be other network devices with input function and output function, which is not limited herein. In Figure 1, the wireless local area network authentication device is connected to the operator's network through an access network, and the wireless local area network authentication device is connected to user terminals, such as mobile phones, tablet computers, web cameras, and other user terminals, through WiFi (Wireless Local Area Network) signals.

The wireless local area network authentication method in the embodiment of the present invention is applied to a wireless local area network authentication device, and uses a voice authentication message for authentication.

FIG. 2 is a flowchart of a wireless local area network authentication method according to an embodiment of the present invention. As shown in FIG. 2 , the wireless local area network authentication method includes steps 101 to 105 .

In step 101, a probe request message sent by a user terminal is received.

The gateway main body of the wireless local area network authentication device may send out wireless local area network signals, and broadcast the wireless local area network information of the gateway main body through beacon frames. The wireless local area network information may include information such as ssid (Service Set Identifier, service set identifier) of the wireless local area network, signal strength of the wireless local area network, and the like, which is not limited herein. The user terminal searches for a wireless local area network signal and tries to access the wireless local area network. Then, the user terminal sends a probe request message (probe request message) to the gateway main body. The gateway main body may receive the probe request information sent by the user terminal, so as to determine the user terminal requesting to access the wireless local area network. In an example, the probe request information includes the identity code of the user terminal, such as the mac address (Media Access Control address, physical address) of the user terminal or the name of the user terminal.

In step 102, a prompt message for authentication is output.

The prompt message may be a voice prompt message or an image display prompt message, which is not limited herein. The prompt message can be triggered by ringing or directly. For example, the gateway body of the wireless LAN authentication device is connected to a fixed phone. When the wireless LAN authentication device generates a prompt message, the fixed phone starts to ring to notify the user to listen to the prompt message. After the user goes off-hook, a voice prompt message is played or an image prompt message is displayed.

For another example, the gateway body of the wireless local area network authentication device is connected to a fixed phone, and when the wireless local area network authentication device generates a prompt message, it directly plays a voice prompt message or displays an image prompt message. It is also possible to trigger to play a voice prompt message or display an image prompt message after receiving a user's key operation or the like. For example, after the user terminal sends a detection request message, the user presses the hands-free key on the fixed phone connected to the gateway main body to trigger the handset of the fixed phone to play the prompt message, or trigger the display screen of the fixed phone to display the prompt message.

A prompt message for prompting the user terminal to perform authentication may be output by the output device of the wireless local area network authentication apparatus. The prompt message may include the identity code of the user terminal or may refer to the name of the user terminal. For example, the output device of the wireless LAN authentication device is the handset of the fixed phone, the mobile phone with the user name "yidong001" requests to access the wireless LAN, and the handset of the fixed phone sends out the voice "currently there is access to the mobile phone yidong001, please perform access authentication" Prompt message, after the user hears the voice prompt message, a voice authentication message is sent; or, after accepting the user's operation, the user terminal sends out a voice authentication message.

In step 103, a voice authentication message is received.

The voice authentication message is a voice message sent by the user or the mobile terminal for authentication. The voice authentication message can be received by the input device of the wireless local area network authentication device, for example, the voice authentication message can be received by the microphone of the fixed phone connected to the gateway body.

In one example, the voice authentication message may include voice information or sonic information. That is to say, the authentication message type may include voice information type or sound wave information type, which will be described in detail later.

In step 104, it is determined whether the voice authentication message meets the preset authentication conditions of the wireless local area network.

Wherein, the gateway body of the wireless local area network authentication device can determine whether the voice authentication message conforms to the preset authentication conditions of the wireless local area network. The preset authentication condition of the wireless local area network may be a preset access verification code, or a preset identification number of a user terminal that allows access, or other types of access passwords or requirements, which are not included here. Not limited.

In step 105, if the voice authentication message meets the preset authentication conditions of the wireless local area network, the user terminal is allowed to access the wireless local area network.

Wherein, if the voice authentication information meets the preset authentication conditions of the wireless local area network, it indicates that the user terminal has the right to access the wireless local area network.

It should be noted that the input device of the wireless local area network authentication device may also be a non-voice input device, such as a key or a dial pad of a fixed phone. After the output device of the wireless LAN authentication device sends out a prompt message, the authentication message can be entered through the keys or dial pad of the fixed phone, for example, the verification code required to connect to the wireless LAN is input through the keys or dial pad of the fixed phone, and the The gateway body may utilize the communication protocol to receive incoming authentication messages transmitted from the landline. For example, the output device connected to the gateway main body outputs a prompt message "Please input verification code A", and the input device connected to the gateway main body receives the authentication message input by the user, and the authentication information includes the verification code input by the user. The input device may receive the authentication message using SIP (Session Initiation Protocol, Session Initiation Protocol). The gateway body of the wireless LAN authentication device compares the input verification code with the preset wireless LAN access verification code. If the input verification code is the same as the preset wireless LAN access verification code, the user terminal is allowed to access the wireless LAN. The preset access verification code of the wireless local area network may be a fixed character string or a dynamically changing character string. The character string can be numbers, letters, or a combination of numbers and letters, etc., which is not limited here. The dynamically changing character string can be generated according to a preset function using the user identification code or time of the user terminal as a variable.

Using a non-voice input device to receive authentication information requires the user to input the authentication message on the input device connected to the gateway body, and does not require the user to input the authentication message on the user terminal. User terminals without input functions such as cameras and some smart home appliances do not need to An external input device can also be connected to a wireless local area network, which simplifies the process of connecting a user terminal without an input function to the wireless local area network. Moreover, users of the WLAN need to operate the WLAN authentication device to access the WLAN, which also prevents unauthorized access users from cracking the authentication conditions of the WLAN (such as the access verification code of the WLAN or access to the WLAN). The security of the wireless local area network can be improved when you access the local area wireless network by entering password, etc.

A wireless local area network authentication method provided by an embodiment of the present invention receives a detection request message sent by a user terminal, outputs a prompt message, receives a voice authentication message, and judges whether the voice authentication message conforms to a preset authentication condition of the wireless local area network. Allow the user terminal to access the wireless local area network. That is to say, in this embodiment of the present invention, the user terminal or the user operating the user terminal can send a voice authentication message without connecting the user terminal to an external input device, and the voice authentication message is received by the wireless local area network authentication device performing authentication judgment. Even a user terminal without an input function can perform wireless local area network authentication without externally connecting an input device, which simplifies the process of the user terminal accessing the wireless local area network.

The voice authentication message in the above embodiment may include voice information or sound information.

In one example, the voice authentication message includes voice information. FIG. 3 is a flowchart of an example of a wireless local area network authentication method in an embodiment of the present invention. The difference between FIG. 3 and FIG. 2 is that step 104 in FIG. 2 may be specifically refined into steps 1041 to 1042 in FIG. 3 , and step 105 in FIG. 2 may be specifically refined as step 1051 in FIG. 3 .

In step 1041, semantic recognition is performed on the speech information to obtain a semantic recognition result.

The voice information is information with certain semantics, which can be sent by the user or sent by the user terminal, which is not limited herein. The frequency range of the voice information is in the range of 20 Hz to 20 kHz. The gateway body of the wireless local area network authentication device extracts the voice information in the voice authentication message and performs semantic recognition, thereby obtaining a semantic recognition result. The semantic recognition result is the meaning conveyed by the speech information.

In step 1042, it is determined whether the semantic recognition result meets the preset authentication conditions of the wireless local area network.

Wherein, according to the detection request message, it can be known which user terminal wants to access the wireless local area network, so in step 1051, if the semantic recognition result meets the preset authentication conditions of the wireless local area network, the user terminal is allowed to access the wireless local area network.

In step 1051, if the semantic recognition result meets the preset authentication conditions of the wireless local area network, the user terminal is allowed to access the wireless local area network.

For example, the prompt message "Please confirm whether to allow access to the network by voice, please answer yes if it is allowed, please answer no if it is not allowed" through the output device, and the user answers "Yes" at the input device connected to the main body of the gateway according to the prompt message. " or "No". The input device receives the voice information answered by the user, and the gateway body performs semantic recognition on the voice information. If the semantic recognition result is "Yes", it indicates that the voice information answered by the user is "Yes", and the user terminal is allowed to access the wireless local area network; if the semantic recognition result is "No", it indicates that the voice information answered by the user is "No", and the user is rejected. The terminal is connected to the wireless local area network. By answering "yes" or "no" to authenticate whether the user terminal is allowed to access the wireless local area network, the password can be prevented from being leaked through voice transmission, and the security level of the wireless local area network authentication is improved.

For another example, the output device sends out a prompt message "Please say the verification code by voice", and the user answers the verification code according to the prompt message at the input device connected to the main body of the gateway, the verification code is included in the voice information, and the input device receives the voice. information, the gateway body performs semantic recognition according to the verification code answered by the user, obtains a string corresponding to the verification code as the semantic recognition result, and compares the string with the preset wireless local area network access verification code. If the character string is the same as the preset WLAN access verification code, the user terminal is allowed to access the WLAN; if the character string is different from the preset WLAN access verification code, the user terminal is denied access to the wireless network.

In the above example, the authentication of the wireless local area network can be completed without the input function of the user terminal, and the authentication process is simpler and faster, and it is well applicable to the authentication of the wireless local area network of various existing user terminals such as smart homes. sex.

In another example, the sound authentication message includes sound wave information, and the sound wave information carries all or part of the feature information of the identity code of the user terminal. FIG. 4 is a flowchart of another example of a wireless local area network authentication method in an embodiment of the present invention. The difference between FIG. 4 and FIG. 2 is that step 104 in FIG. 2 may be specifically refined into steps 1043 to 1044 in FIG. 4 , and step 105 in FIG. 2 may be specifically refined as step 1052 in FIG. 4 .

In step 1043, the acoustic wave information is analyzed to obtain all or part of the feature information of the identity code of the user terminal.

Wherein, all or part of the features of the identity code of the user terminal may be encoded, so that the acoustic wave information carries all or part of the feature information of the identity code of the user terminal. The frequency of the sound wave information needs to be a frequency that can be detected by the input device of the wireless local area network authentication device, which can be within the audible frequency range of the human ear or outside the audible frequency range of the human ear, which is not limited here. The gateway body of the wireless local area network authentication device extracts the sound wave information from the sound authentication message, parses the sound wave information, and obtains all or part of the characteristic information of the identity code of the user terminal. It should be noted that the sound authentication message includes sound wave information, and software modification needs to be performed on the user terminal so that the user terminal can emit sound waves.

In step 1044, it is judged whether all or part of the characteristic information of the parsed and obtained identification code of the user terminal meets the preset authentication conditions of the wireless local area network.

Wherein, the preset authentication condition of the wireless local area network may be a preset authority feature, and it is determined whether all or part of the feature information of the user terminal's identity code obtained by parsing is consistent with the preset authority feature. If there are multiple preset permission features, it is determined whether all or part of the feature information of the user terminal's identity code obtained by parsing is consistent with any one of the preset permission features.

In step 1052, if all or part of the characteristic information of the user terminal's identity code obtained by parsing meets the preset authentication conditions of the wireless local area network, the user terminal is allowed to access the wireless local area network.

Wherein, if the preset authentication condition of the wireless local area network is the preset authority feature, then if all or part of the feature information of the identity code of the user terminal obtained by parsing is consistent with the preset authority feature, the user terminal is allowed to access the into the wireless LAN. When there are multiple preset permission features, the user terminal is allowed to access the wireless local area network if all or part of the feature information of the user terminal's identity code obtained by parsing matches any one of the preset permission features.

For example: the preset permission features include "102579f3" and "0048a376ff39", all the feature information "0048a376ff39" of the identity code of the user terminal obtained by parsing the sound wave information in the voice authentication message B1, from the voice authentication message B2 All feature information "0047422ff390" of the identity code of the user terminal obtained by parsing from the sound wave information, and part of the feature information "0047422ff" of the identity code of the user terminal obtained by parsing from the sound wave information in the voice authentication message B3. After comparison, "0048a376ff39" obtained from the sound wave information in the voice authentication message B1 is exactly the same as one of the preset permission features, allowing the user terminal corresponding to the voice authentication message B1 to access the wireless local area network; The "0047422ff390" obtained by parsing the sound wave information in B2 is different from any of the preset permission features, and the user terminal corresponding to the voice authentication message B2 is refused to access the wireless local area network; from the sound wave information in the voice authentication message B3 The "0047422ff390" obtained by the analysis is different from any of the preset permission features, and the user terminal corresponding to the voice authentication message B2 is refused to access the wireless local area network; "0047422ff" obtained by analyzing the sound wave information in the voice authentication message B3 It is the same as a part of the preset authority feature, allowing the user terminal corresponding to the voice authentication message B3 to access the wireless local area network.

It should be noted that when multiple user terminals request to access the wireless local area network and perform authentication at the same time, if the voice authentication message includes voice information or the authentication message is a non-voice authentication message, then multiple user terminals need to perform wireless local area network authentication in sequence. . That is to say, after the wireless local area network authentication of one user terminal is completed, another user terminal can start to perform the wireless local area network authentication. If the sound authentication message includes sound wave information, multiple user terminals can perform wireless local area network authentication at the same time.

In the above embodiments and examples, the gateway body can be connected to a fixed phone or a mobile phone, the handset of the fixed phone or mobile phone can be used as an output device connected to the gateway body, and the microphone of the fixed phone or mobile phone can be used as an output device connected to the gateway body. input device. The process of WLAN authentication can be performed at the same time as the ringing or talking of a landline or mobile phone.

In addition, in the above embodiments and examples, a timer may also be set, and the set time of the timer is the duration required for the user terminal to perform wireless local area network authentication. However, when the user terminal starts to perform wireless local area network authentication, the timer is started. If the elapsed time of the timer exceeds the set time, it indicates that there is an obstacle or failure in the wireless local area network authentication process, and the wireless local area network authentication process of the user terminal is terminated. A prompt message for prompting the user to re-authenticate the wireless local area network may be issued.

FIG. 5 is a flowchart of a wireless local area network authentication method according to another embodiment of the present invention. The difference between FIG. 5 and FIG. 2 is that the wireless local area network authentication method shown in FIG. 5 further includes steps 106 to 108 .

In step 106, the identity code of the user terminal and the terminal type of the user terminal are obtained, and the corresponding authentication message type is set for the terminal type.

The authentication message type may include voice information or sound wave information, and the authentication message type may also include key input information. The authentication message type is voice information, indicating that the voice authentication message includes voice information; the authentication message type is sound wave information, indicating that the voice authentication message includes acoustic wave information. The identity code of the user terminal and the corresponding terminal type are acquired by the gateway body in the wireless local area network authentication device. The user's setting operation instruction can be received, and the authentication message type corresponding to the terminal type can be specified according to the setting operation instruction. According to the terminal type, the main body of the network management can also set an applicable authentication message type for the terminal type.

In step 107, a corresponding relationship between the identity code and the authentication message type is established.

Wherein, according to the corresponding relationship between the identity code of the user terminal and the terminal type of the user terminal, and the corresponding relationship between the terminal type and the authentication message type, the corresponding relationship between the identity code and the authentication message type is established.

For example, Table 1 is a correspondence table of identity codes, terminal types and authentication message types. Wherein, each row is the corresponding identity code, terminal type and authentication message type. The corresponding relationship between the identity code and the authentication message type can be obtained from Table 1.

Table I

identification code terminal type Authentication message type 0048a376ff01 cell phone sound wave information 0048a376ff02 Camera voice information 0048a376ff03 Smart TV voice information 0048a376ff04 tablet Key input information class

In step 108, the identity authentication message type corresponding to the identity code in the probe request message is obtained according to the identity code in the received probe request message and the correspondence between the identity code and the authentication message type.

Wherein, the detection request message includes the identification code. According to the identity code in the received probe request message, the identity authentication message type corresponding to the identity code in the probe request message is found in the correspondence between the identity code and the authentication message type. The authentication message corresponds to the identity authentication message type. According to the identity authentication message type, the type of the authentication message sent by the user terminal during the wireless local area network authentication process is determined.

For example, the corresponding relationship between the identification code and the authentication message type is shown in Table 1. The identity code in the probe request message is "0048a376ff02", and the identity authentication message type corresponding to the identity code "0048a376ff02" is voice information. Then the voice authentication message received in step 103 includes voice information. The subsequent flow of wireless local area network authentication may adopt the flow of processing a voice authentication message including voice information (ie, step 1041 , step 1042 and step 1051 ).
