Embodiment
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, below in conjunction with the drawings and specific embodiments the embodiment of the invention is described in further detail.
The invention provides a kind of method of utilizing near-field communication technology NFC to realize inter-terminal data communication, under certain agreement is supported, realization is carried out writing operation by NFC terminal A to the smart card among the NFC terminal B, perhaps, NFC terminal A carries out the operations such as Data Update to the smart card among the NFC terminal B under the support on backstage.
NFC is developed by non-contact radio-frequency identification RFID and interconnection and interflow Technology Integration, by the function of integrated induction formula card reader, induction type card and point-to-point communication on one chip, utilize portable terminal to realize mobile payment, electronic bill, gate inhibition, mobile identification, the application such as false proof.NFC adopts 13.56Mhz as the short-range communication frequency standard, the radio frequency standard such as compatible ISO14443, ISO15693, Felica.
Near-field communication NFC business support mode card, card reader pattern and point-to-point communication pattern, mode card generally is used for bank card, accumulating card, all kinds of stored value cards etc., the card reader pattern is generally carried out reading tag advertisement, the application such as false proof, and the point-to-point communication pattern then provides the services such as data transmission, game between two NFC equipment.
Smart card Smart Card is a kind of of IC-card (integrated circuit card), can be divided into according to the industry of using: telecom intelligent card (the GSM mobile communication is called SIM card or usim card), identity card intelligent card, gate inhibition's smart card etc.
The SIM card (usim card) of specifically using for GSM, at present writing operation includes but are not limited to the personal datas such as the integrated circuit card identification code ICCID, the international mobile subscriber identity IMSI that write, upgrade in the smart card, key K I code, OPC, sms center, also can comprise preservation book, note in the SIM card, and the STK menu that presets of SIM card and such as application such as the mobile phone wallet preserved in java card or the SWP card, bank debit and credit note, electronic ticket, stored value card, personal certificates, also can comprise such as the information such as personal account relevant with borrowing credit card.
The building-block of logic that the present invention writes card to the smart card among the NFC terminal B by NFC terminal A as shown in Figure 1.
NFC terminal A can be the mobile phone with NFC function, also can be the card reader with NFC function that can connect the equipment such as computing machine.NFC terminal B can be the mobile phone with NFC function, also can be the autonomous device that has the NFC function, can insert smart card and smart card is operated.NFC terminal A and NFC terminal B use 13.56Mhz or other agreed frequencies to carry out radio communication, and communication protocol can adopt:
(1) ISO144443Type A/B: non-contact card communication protocol;
(2) ISO18092:NFC interface and agreement;
(3) NFC Forum NDEF(NFC Data Exchange Format): the form of NFC exchanges data;
(4) NFC Forum RTD(NFC Record Type Definition): the NFC data type;
(5) NFC Forum Type1～4Tag: to the operating protocol of Class1～4 labels;
(6) NFC Forum LLCP(Logical Link Control Protocol Technical): point-to-point logic link control protocol;
(7) NFC Forum SNEP(Simple NDEF Exchange Protocol): the Point-to-Point Data exchange agreement.
Also can adopt specialized protocol, realize safe and reliable communication between NFC terminal A and the NFC terminal B.
NFC terminal A in the situation with mobile communication function, can also utilize the smart card in the mobile phone to do safety certification except the function that possesses foregoing description, further guarantees the security of data and control.Following two kinds of operator schemes can be arranged: a kind of is application data or the personal data that pre-stored needs write smart card, when establishing a communications link with NFC terminal B by rendezvous protocol with the data copy among the NFC terminal A to NFC terminal B smart card, in copy procedure, can mutually carry out legitimacy authentication and data check, guarantee the legitimacy and the data integrity that write; Another kind is that NFC terminal A is connected with service supporting platform foundation by wireless or wired mode in real time, after service supporting platform obtains data the smart card the NFC terminal B is write the operations such as card.
NFC terminal B is except having the foregoing description function, it can be a mobile phone with NFC function, can be the terminal that only has the NFC function also, comprising intelligent card socket, can insert smart card and smart card be carried out the operation of limited authority or all authorities.NFC terminal B can have two kinds of mode of operations: a kind of is channel pattern, namely realizes the data penetration transmission between NFC and the smart card; Another kind is to receive by NFC by interfaces such as ISO7816 smart card to be carried out writing operation after instruction is processed, and operating result is fed back to NFC terminal A by NFC.
＜embodiment 1 〉
Offline copies pattern: as shown in Figure 2, NFC terminal A sets up by communication link and business platform and contacts, communication link can adopt wired or wireless mode, communication protocol by agreement is downloaded application or the data that need to write smart card in advance, difference according to application can be that a concrete NFC uses, also can be concrete data, take the GSM network as example, can be to comprise the intelligent card datas relevant with mobile number such as IMSI, KI.Behind terminal A success downloading data, as required, the smart card that needs write operation is inserted among the terminal B, as shown in Figure 3, terminal A and terminal B be placed on set up in the distance that NFC communicates by letter, write application or the data downloaded in advance among the terminal A in the smart card of terminal B by predefined communication protocol, specifically for the GSM network intelligence, the data of downloading are under the support of end application or operating system, write in the smart card with forms such as data SMSs, smart card upgrades the IMSI of smart card according to the communication protocol of making an appointment, the data such as KI, and return or failure information according to related protocol.
＜embodiment 2 〉
The online mode card of writing of mobile phone with NFC function, as shown in Figure 4: the NFC mobile phone A is utilized cordless communication network and service supporting platform to set up and is contacted, set up by NFC with the NFC mobile phone B simultaneously and contact, according to service needed, carry out writing operation from the support platform downloading data and to the smart card the mobile phone B, write the card result feedback to service supporting platform.
In order to increase data security; mobile phone A can utilize smart card wherein that the data of aerial transmission are encrypted protection; wherein; cryptographic algorithm can adopt the 3DES symmetric encipherment algorithm; also can adopt rivest, shamir, adelman; can also adopt privately owned enciphering and deciphering algorithm, specifically adopt which kind of cryptographic algorithm to select according to the needs of the security of using, the present invention does not limit this.
＜embodiment 3 〉
