Description
Technical field
The present invention relates to the communications field, specifically provided the new type user identification module of a kind of employing general-purpose serial bus USB (Universal Serial Bus) interface.
Background technology
Subscriber Identity Module has been stored the data of user identity identification and user's private data, and its basic purposes is to guarantee that each communication network correctly discerns mobile subscriber's identity.Can the access communications network when legal users identification card and mobile phone use jointly.The Secure Application of Subscriber Identity Module comprises: the mutual authentication of network and Subscriber Identity Module, to Subscriber Identity Module proof user, file condition and access rule, to the dialogue function from network parameter.The demand that comprises customer-side, data transmission, version information, telephone directory, calling (dial-out/access) details, cell information etc. are used in the service of Subscriber Identity Module.
International ISO/IEC 7816 standards that regulation, host-host protocol etc. all are the employing intellective IC cards are deposited and visited to logic, physical characteristic, the data file of Subscriber Identity Module in present existing communication network, is called IC system Subscriber Identity Module (abbreviation IC-card) in this article.
IC-card is connected what use when carrying out information exchange by the IC-card read write line with mobile phone all be asynchronous communication model, and because the FPDP of smart card has only one, this information exchange also can only be adopted semiduplex mode, at any one time promptly, can only there be a side (smart card or read-write equipment) sending data on the FPDP at most.This characteristic has greatly restricted the adding of new business, for example: the cryptographic algorithm in the card can only adopt the block encryption mode at present, if carry out end-to-end stream cipher duplex mode between card and mobile phone communicates by letter and transmits the cleartext information of ciphertext and deciphering, present mechanism can't realize, so also just can't utilize at all and adopt the external encryption card to realize the advantage that the stream cipher computing brings.
The IC-card read write line is difficult to the multithreading operation of support to IC-card, can't make full use of multitask, the multi-process performance of operating system so, can only realize limited application.
The data transfer rate of top IC-card interface standard possibly can't satisfy in the future very high required communication rate, becomes a bottleneck in the design, and this is a defective of interface standard itself.This defective is from two parts: actual speed of communicating by letter between mobile phone terminal and the IC-card read write line and the message transmission rate between IC-card read write line and the IC-card, a few KBps-tens KBps can only be according to test by the traffic rate after these two interfaces, the order of magnitude of MBps can't be reached.
If the system of the IC by mobile phone Subscriber Identity Module is when carrying out Data Update operation or card test on computers, need in computer, increase an IC-card read write line, can't utilize the computer present interfaces that Subscriber Identity Module is operated, be unfavorable for so very much the expansion of serving.
Information exchange between read-write terminal and IC-card is order-reply structure, and read-write terminal sends one and orders IC-card, and the IC-card fill order also returns to read-write terminal with response message.Press the definition of ISO/IEC7816 related standards, an Application Protocol Data Unit (APDU) or contain command information or contain response message, APDU can be understood as the minimum unit of information of communication transmission between read-write terminal and the IC-card, this limited data mode can't satisfy the requirement of big transfer of data, so need other forms of data mode to satisfy special requirement, for example: the interrupted transmission of encrypting ciphertext and clear data in the stream cipher encrypting.
Simultaneously this standard only is used in IC-card and is connected communication with IC-card read write line in the mobile phone terminal, so when needing to connect the equipment of other interfaces, at all can't flexible expansion, for example: can't be connected with computer or other mobile phones by existing the port with mobile phone, IC system Subscriber Identity Module also can't directly connect with computer, this needs an extra IC-card read write line, and these two problems are owing to only solidified the defective that these ISO/IEC 7816 standard interfaces are brought in the mobile phone at present.And IC system Subscriber Identity Module itself has the problem that more needs overcome, and uses two angle explanations from exploitation and user below.
Shortcoming in the exploitation: because that the IC-card read write line of IC-card and curing carries out is connected in series, the limitation of any one part is all greatly restricting the raising of overall performance so.The reading and writing data speed of IC-card can't satisfy in the future very high data throughput rate.
Shortcoming in the application: the memory space of IC-card is very limited, can't store more user data and business datum, for example: can't store more PKI and private key to information security data such as, digital certificates, make and to adopt with better function and comprehensive information security system, further strengthen safety function, carry out the very high service application of some fail safes and mobility, use as mobile PKI etc.
Can't or be difficult to Subscriber Identity Module is carried out overall operations, as personal information that will be wherein, telephone number, address book, pin sign indicating number or whole Subscriber Identity Module storage in computer or will be with in the personal information input Subscriber Identity Module in batches, need in computer, write and finish these functions at the program of IC interface, and write the IC interface routine is the work of wasting time and energy very much, face again can't be between each tame manufacturer general problem, therefore lack a kind of high efficient and flexible and general interface at present and make coding efficient and general.
