Abstract

Mobile environment has been used in large area range of network. In order to secure communication, a number of schemes have been proposed. The typical schemes are two-party authentication key exchange (2PAKE) protocols. It is based on elliptic curve cryptosystem. The main weakness of the protocol is that attackers have the ability to impersonate a legal user at any time. In addition, it is vulnerable to the public key problem and unknown key share attack. In this paper, we propose a 2PAKE protocol. Our protocol is indeed safer and meets the needs. Hence, the proposed protocol has a great contribution to the area of mobile environment.
