Title: The Optimized Authentication Signaling Flow for 3GPP-WLAN Heterogeneous Interworking
Abstract: This paper mainly focuses on the authentication protocol EAP-AKA(Extensible Authentication Protocol Method for UMTS Authentication and Key Agreement) in the integration of 3GPP(The Third Generation Partnership Project)and WLAN(Wireless Local Network).An authentication mathematical model for 3GPP-WLAN was established.Through analyzing the authentication protocol,it is pointed out that the number K of AVs(authentication vectors) obtained from authentication center every time and the number of re-authentication can affect the authentication signaling cost.A novel adaptive K select mechanism was proposed by considering the re-authentication procedure.The novel scheme utilizes the termin-al's total authentication times,the number of re-authentication and the value of K in previous WLAN to infer the proper value of K in current WLAN.The simulation result shows that the new scheme can efficiently reduce the authentication signaling cost compared with the fixed K authentication mechanism.
