Description

Double integrated circuit card system

Technical field

The utility model relates to a kind of double integrated circuit cartoon authentication module, is applied to wireless telecommunications or financial transaction Verification System.Particularly use relevant for integrated circuit (IC) chip card user identification module, can increase the additional application of wireless telecommunications, and can handle double integrated circuit chip card subscriber identification module simultaneously, and use about the identification of smart card, be widely used in authentications such as finance, transaction with credit, to promote convenience.

Background technology

In general, smart card is widely used in two fields, and one is the subscriber identification module (Subscriber IdentityModule:SIM) in field of wireless communication, and two is status Verification System such as fiscard, ATM card or health insurance cards or the like.SIM card is to use among mobile communication device.Every is used the usefulness of Radio Network System such as GSM or cdma system mobile phone that the SIM card that is provided by relevant telecommunication service company is provided per family, it stores all relevant users' data, comprise user's telephone number, telephone directory, call blocking ... Deng, and PIN (PIN) and personal unblocking code (PUK) etc.And it is consistent with the stored data of database in the network system.Yet, use the GSM communication system to carry out communication must to adopt～SIM card of opening and closing method, could insert affiliated GSM communication network and carry out information exchange, otherwise can not enter.

Subscriber identification module (SIM card) is generally lesser calorie, is of a size of 25mm * 15mm, and what still really use is the part of band copper contact.When SIM card is connected with mobile phone, the rarest 5 junctions.SIM card partly is made up of CPU, RAM, ROM, EEPROM or flash memory (Flash) and serial communication unit etc. five.

Moreover, when mobile phone power-on, the legitimacy of Radio Network System automatic inspection SIM card, and after system is approved under obtaining, just provide service for the user.As everyone knows, the information in the above-mentioned subscriber identification module of being stored in comprise action user discrimination (IMSI), personal user's key (individualsubscriber key, Ki), identifying algorithm (authenticationalgorithm), individual identification password (PIN) and other permanent or temporary transient data.But in existing technology, SIM card only limits to store the IMSI and the Ki of the wireless telecommunication services company that issues this SIM card, and the user can't increase the IMSI and the Ki of another wireless network telecommunications service company freely in SIM card.

On the other hand, the stored data of SIM card comprises:

(1) gsm system control channel data: the frequency data of system (network provider) distribution that obtains promptly.

(2) international moving with user identification code (IMSI) and interim identification code (TMSI): international mobile subscriber identification (IMSI) is printed on the card, be global Unified coding and the unique number that can discern the user, it can make the Network Recognition user attaching in which country, as Hong Kong 898520, China 898600, whether be stored value card etc., but be not equal to user's phone number.Interim identification code (TMSI) is the temporary number that system assignment is given the user, and in standby, what use in the conversation only is this temporary number.

(3) user's key and secret algorithm: utilize the key that is storing the user in the SIM card corresponding one by one with user identification code with secret algorithm, and in there is the database of SIM card and telecommunications service company respectively in secret algorithm, it is each when the user enters system, system is for confirming user's identity, carry out producing stochastic variable after a series of safety certification, and and user's key pass through cryptographic calculation together; Whether consistent check again with the result of calculation of database by wireless channel.Purpose is to differentiate user's identity, in case the disabled user enters network.

(4) PIN (PIN) and to separate PIN (PUK): PIN (Personal Identification Number) PIN be the password of encrypting usefulness for SIM card.And the purposes of PUK (Personal UnlockingKey) is as follows: after three mistakes of PIN input, then pin SIM card, in case usurp; Need PUK to carry out release, if continuous 10 input errors of PUK, SIM promptly lost efficacy forever.Though the data in the SIM card can not change, still have the part space to make telephone directory and SMS (news in brief) usefulness for the user, but the finite capacity in this space, the user can't expand telephone directory or news in brief storage area to SIM card under existing technology.

(5) SIM card application tool group (STK, SIM Tool Kit) use: STK is a standard of extensively being supported by Portable mobile device and SIM card, for cooperating the sale room of SIM card, telecommunications service company offers user's action value-added tax function, STK uses and carries out value added application function such as Mobile Banking by program stored in the SIM card, action security and action message inquiry (Information On Demand:IOD) or the like.STK use can be before the SIM card distribution with regard to burning in the internal memory of SIM card, also can download in the internal memory of SIM card through wireless or cable network voluntarily by the user in SIM card distribution back.The obstacle that this prior art is implemented at present is that all SIMSTK application all must come keyholed back plate by telecommunications service company, and plan the support of SIM card to value added service by telecommunications service company, third-party wireless application supplier or second telecommunications service company then must reach an agreement with the telecommunications service company of distribution SIM card after, could be on the SIM card technology platform that it is set up with burning in advance in the SIM card internal memory, or the mode of software download is issued its application.Wireless network application user then need upgrade its existing SIM card and could use this service under tripartite common protocol.This obstacle has caused wireless network to use the logistics costs of distribution and the monopolization of telecommunications service company, makes wireless network use and is difficult to effectively be promoted by the third party.

In addition, conventional smart card is a kilocalorie, is of a size of 84mm * 54mm, generally is applied to financial transaction system such as fiscard, credit card, ATM card; Or status Verification System such as health insurance cards.Partly smart card comprises among the plastic plate that an antenna loop is around in card, so that contactless application to be provided, is called contactless card; Usually be applied to gate control, or traffic charging system, for example national highway E-payment system (Electronic TollCollection:ETC).Above-mentioned national highway E-payment system (ETC) is to adopt Automatic Vehicle Identification (Automatic VehicleIdentification:AVI), Automatic Vehicle Classification (AutomaticVehicle Classification:AVC) and image enforcement system front end associated communication science and technology such as (Video Enforcement System:VES), with be disposed at the scanning that interacts of On-Board Unit (OBU-On BoardUnit) in the car, and through rear end account service processing system, automatically withhold, the action of charge, when allowing vehicle pay the fees fixed point in the charge station of passing through etc., do not need ramp to stop, to save traffic time.

Fig. 1 is the schematic diagram according to an integrated circuit (IC) chip card 10 of known technology.Integrated circuit (IC) chip card 10 has an integrated circuit (IC) chip 14, and wherein the surface of a substrate 11 is adhered to or be embedded in to integrated circuit (IC) chip 14.And substrate 11 comprises a cutting angle 13, integrated circuit (IC) chip card 10 is inserted among the portable apparatus with suitable direction in order to the guiding user.
