Abstract: Systems and methods of securing GSM wireless communications between a networ k and a subscriber station are disclosed. One embodiment creates authenticatio n triplets due to expire after a certain amount of time such that they may not be used indefinitely by an attacker who intercepts them.

Abstract: Systems and methods of securing wireless communications between a network and a subscriber station include inserting a marker denoting an encryption type within a random value used for authentication, calculating a first session key and a first response value as a function of the random value, then calculating a second session key and a second response value as a function of the random value, first session key and first response value. The two levels of session keys and response values may be used by upgraded subscriber stations and network access points to prevent attackers from intercepting authentication triplets.
