A Fast-Roaming Authentication Method Using ID-Based Encryption for the 3G User Roaming between WLANs
Ze Wang, Yan Zhang, Wenju Liu, Yongzhen Ke · 2009
EAP-AKA is a secure access protocol in the 3GPP WLAN-3G interworking scheme which can realize bi-directional authentication between 3G users and 3G networks, however WLAN access networks in the middle position are not authenticated, and the 3G-UE master key updating strategy is not proposed, and the cost of the 3G user roaming between WLANs is high. The new protocol implements the authentication for WLAN access networks, and designs the master key updating strategy through ID-based encryption and ticket technology, and proposes a fast-roaming authentication method without the participation of 3G networks.
