Description
Technical field
The present invention relates to intelligent network business, relate in particular to a kind of stolen intelligent network business of user identity that prevents and realize system and method.
Background technology
The GSM network protects legal contracted user to use the network service by authentication mechanism at present.GSM (Global System for Mobile Communications) system adopts tlv triple (IMSI/RAND/SRES) to carry out authentication, (the International Mobile SubscriberIdentification Number of IMSI in the tlv triple, the international mobile subscriber identifier) is stored in SIM (Subscriber IdentityModule, subscriber identification module) card and HLR/AuC (Home Location Register/AuthenticationCenter, attaching position register/AUC) in, RAND is the random number that HLR/AuC produces, SRES (symbol response) is that SIM card and HLR/AuC both sides are respectively according to key K i, IMSI, the authentication arithmetic (as A3) of RAND and both sides' agreement calculates, Ki is stored among SIM card and the HLR/AuC, for increasing reliability, Ki is not in the transmission of eating dishes without rice or wine.Both sides are delivered to MSC/VLR (Mobile Switch Center/Visiting Location Register with the SRES that calculates respectively, mobile switching center) in, compare by MSC/VLR, thereby determine whether the user has legal identity.As can be seen, IMSI is the identification code that the user has legal identity.
In addition, gsm system also provides the affirmation function for equipment identities, promptly terminal is confirmed.The identity code of terminal is IMEI (International Mobile Equipment Identity, an international mobile device identifier), is stored among the EIR (Equipment Identity Register, device identification number register).EIR provides white list, blacklist and the gray list based on IMEI, makes system provide professional for legal mobile phone, also can tackle or follow the tracks of illegal cell phone apparatus simultaneously.EIR is the optional equipment of system, does not all adopt this equipment in the GSM network of China at present.
In the gsm system that EIR is not set, the affirmation of user's legal identity is needed IMSI, Ki and 3 essential informations of authentication arithmetic, these 3 essential informations are stored among SIM card and the HLR/AuC simultaneously.For the user, SIM card is vital proof of identification.For gsm system, when MS (travelling carriage) start, occurrence positions variation and professional application, will trigger authorizing procedure, legal proof of identification is provided, in time notify position and/or the state variation of HLR/AuC self simultaneously.Gsm system is by having unique IMSI can use legitimate traffic in the MS information assurance system that preserves among the HLR/AuC.At present, occur " swiping the card " equipment on the market, promptly duplicate SIM card fully by special installation, because duplicated SIM card has legal identity information, system can't identify.If SIM card by fraudulent copying, hold so the user who duplicates SIM card can usurp validated user identity enjoy network service and can't be by system identification, the interests of validated user will be encroached on.
In the gsm system of EIR was set, EIR only provided the affirmation based on IMEI.Because the IMSI that stores among IMEI that stores among the EIR and the HLR/AuC is separate, use the terminal of normal channel purchase then to become validated user as long as hold the user who duplicates SIM card, also can't be gone out by system identification.
Patent application " a kind of system and method for user terminal identity identification " (application number: 200610032928.3) disclose the implementation that a kind of user terminal identity is discerned, this scheme increases antitheft molding piece on switching equipment, this module sends the prompting of input authentication information to caller equipment after receiving called number, the authorization information of uploading according to caller equipment judges whether user terminal is legal terminal again, if be legal terminal, then connect called equipment; Open antitheft molding piece, be used to open the authentication of calling; Cancel antitheft molding piece, be used to cancel the authentication of calling; Revise the identity information authentication module, be used for revising authentication authorization information when calling out.This implementation utilizes password to control, and all triggers business when per call, all needs mutual with the user when per call, causes waste of network resources.
