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)
We present a multilevel/genetic circuit partitioning algorithm that utilizes the Metis graph partitioning package [13], which had been previously applied to nite-element graphs. Our new technique produces better results than Metis alone, and also produces bipartitionings that are competitive with the recent methods of [17], [16] and [6] while using less CPU(More)
3G/UMTS-WLAN heterogeneous mobile network is a complementary platform for the trend of Beyond3G (B3G) wireless communications. However, the design of a secured and fast re-authentication protocol in 3G/UMTS-WLAN interworking networks is a challenging task. Although EAP authentication and key agreement (EAP-AKA) protocol is adopted by the third generation(More)
