Abstract:
1. A method for multiple Extensible Authentication Protocol (EAP)-based authentications in a wireless communication system, the method comprising: generating a first master session key (MSK) in a first EAP-based authentication for a first-type access; generating a first temporal session key (TSK) from the first master session key (MSK); performing a second EAP-based authentication, using the first temporal session key (TSK), for a second-type access; providing first-type access and second-type access after the first and second EAP-based authentications are successfully completed; generating a second master session key (MSK) in the second EAP-based authentication; and generating a second temporal session key (TSK) from the second master session key (MSK), wherein the second temporal session key (TSK) is used in a third EAP-based authentication.
