In 2011, Khan et al. identified that Wang et al. scheme could not achieve user anonymity and had many practical pitfalls, In addition, Khan et al. presented an enhanced scheme to eliminate the aforementioned defects.In this article, we point out that Khan et al.'s scheme is incapable to provide user anonymity and suffers from forgery attack, offline password guessing attack.Besides, a new authentication scheme for anonymous users using elliptic curves cryptosystem is presented, which could withstand various types of network attacks and is more suitable for mobile application scenarios where resources constrained and security concerned.
