Authentication mechanism is one of the core concepts of wireless LAN is its. An 802.1X/EAP framework allows a various specific methods to be made used for authentication .Among those EAP-AKA having traditional challenge and response method. It also uses the mechanism of symmetric key cryptography. This study analyses the widely deployed EAP-AKA protocols defined inRFC's, used in interworking networks. This study mainly focus on the fast EAP-AKA protocol which reduces multiple rounds of challenge and response method by maintaining the identity of visited domain and by generating local keys for secure handover, thus resulting in fast handover. © Medwell Journals, 2016.
