Abstract

We analyze several mutual authentication and key exchange protocols (MAKEPs) in this paper, and present a number of desirable properties of such protocols for secure wireless communications. To address the security problems of existing protocols, we propose an improved version of MAKEP known as EC-MAKEP. Apart from providing the desired security features supported by the existing protocols, the proposed protocol supports user anonymity, and forward secrecy which are not supported by many of the previously proposed protocols. Further, the proposed protocol outperforms ES-MAKEP, the latest improved version of MAKEP, in terms of computation cost and communication bandwidth.
