Recently, Tsai et al. proposed an improved password authentication scheme for smart card. Their scheme is more secure than the other previous schemes. In this paper, we show Tsai et al.’s scheme is vulnerable to password guessing attack and has computational overhead. Furthermore, we propose an enhanced password authentication scheme to eliminate the security vulnerability and enhance the overhead. By presenting concrete analysis of security and performance, we show that the proposed scheme cannot only resist various well known attacks, but also is more efficient than the other related works, and thus is feasible for practical applications.
