Background technology
In wireless communication system, for guaranteeing the fail safe of communication, user terminal communicates with the base station if desired, and then both must set up identical authorization key context, i.e. AK context.Described AK context comprises following information:
Authorization key (AK); authorization key sign (AKID); authorization key sequence number (AK Sequence Number); authorization key life cycle (AK Lifetime); antithesis master key sequence number (PMK Sequence Number); uplink message integrity protection key (HMAC/CMAC_KEY_U); uplink message prevents Replay Attack packet number (HMAC/CMAC_PN_U; be called for short PN_U); downlinlc message integrity protection key (HMAC/CMAC_KEY_D); downlinlc message prevents Replay Attack packet number (HMAC/CMAC_PN_D is called for short PN_D); key-encrypting key (KEK); integrality encryption key (EIK).
Wherein, described HMAC/CMAC_KEY_U, HMAC/CMAC_KEY_D are calculated according to AK, terminal media access control (MAC) address, Base Station Identification by the base station, and being respectively applied for provides integrity protection to uplink downlink message;
Described PN_U and PN_D are two 32 digit counters, and when the AK context was set up, the value of described two counters all was 0, and afterwards, every use HMAC/CMAC_KEY_U provides integrity protection one time to upstream message, and terminal just increases by 1 to the value of PN_U; Every use HMAC/CMAC_KEY_D provides integrity protection one time to downstream message, and the base station just increases by 1 to the value of PN_D.If the numerical space of PN_U or PN_D exhausts (be in these two values any arrive in 2^32-1), or AK expires life cycle in the AK context, then this AK finishes life cycle.Be to guarantee not interrupting of communication process, before AK finishes life cycle, should apply for new AK again.
