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.
