Abstract
The utility model provides an intelligent security SIM card, includes SIM chip, NFC chip and NFC antenna, wherein the NFC chip is connected with the NFC antenna, still including encryption and decryption chip and memory chip, wherein the encryption and decryption chip is connected with NFC chip and memory chip respectively, and the SIM chip is connected with the encryption and decryption chip simultaneously. Verify through NFC that the equipment after mating can read the data of saving among the memory chip, perhaps to writing in data among the memory chip into, the process of writing in into and read of data all needs to encrypt or decrypt the processing via specific encryption and decryption chip, thereby data security has been guaranteed, be in under the condition of non -contact with this SIM card at external equipment, the transmission of quantity performed certificate, even if capture the relevant information in the transmission course, also can't decrypt under the prerequisite that does not obtain corresponding encryption and decryption chip, therefore be applicable to the drawing fast and shift of data of high security.
Description
Technical field
The utility model relates to the technical field of data transmission security, is a kind of intelligent and safe SIM card specifically.
Background technology
SIM card is the abbreviation of (SubscriberIdentityModule client identification module), and also referred to as subscriber identification card, smart card, GSM digital mobile telephone must be loaded onto this card and can use. Computer chip stores the information of digital mobile phone client, the contents such as the key of encryption and the telephone book of user, can differentiate for GSM network client identity, and voice encrypt information when client is conversed.
NFC is a kind of short range high frequency wireless communication technology, and electronics can be allowed to carry out mutually the Point-to-Point Data Transmission of noncontact formula. This technology is by non-contact radio-frequency recognition technology RFID(RadioFrequencyIDentification) develop, backward compatible RFID technique simultaneously. Owing to possessing higher security, therefore NFC technique is considered to mobile payment aspect very big application prospect.
Current NFC device is formed primarily of NFC chip and NFC antenna, and wherein NFC chip has communication function and certain computing power, and NFC antenna is then a kind of near field coupled antenna, is in general that pickup coil collocation magneticthin film is formed.
Support that the equipment of NFC initiatively or under Passive Mode can transmit data. In the active mode, using doing, other NFC device is carried out read or write operation to NFC device by the radio-frequency field initiatively sending oneself as RFID card reader. And in the passive mode, NFC device as being read or write data as a rfid card by other NFC device, passive response in the radio-frequency field that can only send in other NFC device exactly in simple terms. NFC chip in SIM card with NFC chip of the prior art and SIM are relatively independent two portions, and independent work also independent uses.
Practical novel content
The technical problems to be solved in the utility model is to provide a kind of intelligent and safe SIM card.
The utility model is the technical scheme that the technical problem existed in solution known technology is taked:
Intelligent and safe SIM card of the present utility model, comprises SIM chip, NFC chip and NFC antenna, and wherein NFC chip is connected with NFC antenna, also includes deciphering chip and storage chip; Wherein deciphering chip is connected with storage chip with NFC chip respectively, and SIM chip is connected with deciphering chip simultaneously.
The utility model can also adopt following technical measures:
NFC chip has authentication module.
SIM chip and deciphering chip one_to_one corresponding.
The advantage that the utility model has and positively effect be:
In intelligent and safe SIM card of the present utility model, storage chip is connected with NFC chip by deciphering chip, the data stored are got in storage chip by the device-readable after NFC checking pairing, or in storage chip, write data, the write of data and reading process all need to be encrypted or decryption processing via specific deciphering chip, thus ensure that the security of data, under peripheral equipment and this SIM card are in non-contacting situation, complete the transmission of data, even if intercepting and capturing relevant information in transmitting procedure, also cannot be decrypted under the prerequisite not obtaining corresponding deciphering chip, thus rapid extraction and the transfer of the data of high security it is applicable to. in addition, owing to SIM chip is connected with deciphering chip, it is also possible to the noncontact formula realizing data in SIM card reads.
Accompanying drawing explanation
Fig. 1 is the configuration diagram of intelligent and safe SIM card of the present utility model.
Embodiment
Below by way of the drawings and specific embodiments, the technical solution of the utility model is described in detail.
As shown in Figure 1, intelligent and safe SIM card of the present utility model, comprises SIM chip, NFC chip and NFC antenna, and wherein NFC chip is connected with NFC antenna, also includes deciphering chip and storage chip; Wherein deciphering chip is connected with storage chip with NFC chip respectively, and SIM chip is connected with deciphering chip simultaneously.
NFC chip has authentication module, the verification of shaking hands of SIM card and external NFC devices can be completed by the authentication module of NFC chip.
In addition, SIM chip and deciphering chip one_to_one corresponding, different SIM chip adopts different deciphering chips, thus further increases the security of encryption and decryption process.
In intelligent and safe SIM card of the present utility model, storage chip is connected with NFC chip by deciphering chip, the data stored are got in storage chip by the device-readable after NFC checking pairing, or in storage chip, write data, the write of data and reading process all need to be encrypted or decryption processing via specific deciphering chip, thus ensure that the security of data, under peripheral equipment and this SIM card are in non-contacting situation, complete the transmission of data, even if intercepting and capturing relevant information in transmitting procedure, also cannot be decrypted under the prerequisite not obtaining corresponding deciphering chip, thus rapid extraction and the transfer of the data of high security it is applicable to. in addition, owing to SIM chip is connected with deciphering chip, it is also possible to the noncontact formula realizing data in SIM card reads.
The above, it it is only better embodiment of the present utility model, not the utility model is done any restriction in form, although the utility model is with better embodiment openly as above, but, and be not used to limit the utility model, any those skilled in the art, do not departing within the scope of technical solutions of the utility model, certainly the technology contents of announcement can be utilized to make a little change or modification, become the equivalent embodiment of equivalent variations, in every case it is the content not departing from technical solutions of the utility model, the any simple modification above embodiment done according to technical spirit of the present utility model, equivalent variations and modification, all belong in the scope of technical solutions of the utility model.
