3G/UMTS-WLAN heterogeneous mobile network is a complementary platform for the trend of Beyond-3G (B3G) wireless data communications. However, the design of a securing authentication protocol in 3G/UMTS-WLAN heterogeneous mobile networks is a challenging task. Even though EAP authentication and key agreement protocol (EAP-AKA) is adopted by 3rd generation(More)
In recently years, Radio Frequency Identification (RFID) system in low-cost communication applications is growing rapidly and deploying widely. Regarding the low-cost RFID device, the design of easy and simplified circuits must be concerned first, moreover, integrity and encryption issues also must be considered to avoid an illegal tampering and to secure(More)
—In GSM-WLAN heterogeneous networks, the authentication efficiency is one of the drawbacks for message transaction and processing in the RADIUS server. This paper proposed two fast authentication schemes, based on the EAP-SIM mechanism, to improve the authentication efficiency by balancing the message transaction loads and processing loads among the RADIUS(More)
