Performance Analysis of Modified EAP-AKA Protocol Based on EAP-TLS for Beyond 3G Wireless Networks

For future heterogeneous system the security is the one of the most important problem. Interworking of Universal Mobile Telecommunication Systems (UMTS) and wireless local area networks (WLANs) establishes new challenges in the design of secured protocol. Our approach focuses on Public Key Infrastructure (PKI) to be integrated in beyond 3G network. The Extensible Authentication Protocol –Transport layer security (EAP-TLS) protocol is a standard framework supporting multiple types of authentication methods and it provides a certificate based mutual authentication. This paper analyzed the modification of Extensible Authentication Protocol-Authentication key agreement (EAP_AKA) mechanism based on EAP-TLS. In addition the performance of this modified protocol is analyzed with authentication cost under different mobility and traffic pattern.
