Even if EAP-AKA protocol provides authentication services in UMTS-WLAN interworking networks a fast re-authentication of EAP-AKA protocol still cannot overcome high re-authentication delays and delaysensitive applications. Because a mobile user is authenticated by a remote RADIUS or a HLR HSS both resided in 3G-UMTS home networks whatever a full authentication or a fast re-authentication is occurred. It causes that huge re-authentication session loads and cryptographic operation loads concentrated on the RADIUS and the HLR HSS. In addition such an inefficient authentication re-authentication protocol also causes long authentication re-authentication latency. Therefore this article proposes a novel protocol named fast iterative localized reauthentication FIL re-authentication to replace the fast re-authentication of EAP-AKA protocol. The proposed protocol not only has minor modifications to attain the same security level as EAP-AKA but it uses both localized re-authentication process and iterative process within the AP to handle the fast re-authentication locally and iteratively for speeding up the re-authentication. Additionally the IEEE WLAN simulation mode based on Network Simulator 2 is used for proving a valid implementation and for analyzing the performance of the proposed protocol. It shows superior results in comparison to .
