Abstract
Many smart-card-based remote authentication schemes have been proposed recently. In 2004, Yoon et al. presented an improved scheme which is the leading of a research track started from Sun, 2000. In this paper, we illustrate that Yoon et al.'s scheme is vulnerable to the parallel session attack and propose an enhancement of the scheme to resist that attack. In our scheme the parties further establish a forward-secure session key by employing only hash functions to protect the subsequent communications. We also demonstrate that our scheme has better security in comparison to other related works, while it does not incur much computational cost © 2007 Springer

Abstract
In 2003, Wu and Chieu proposed a user friendly remote authentication scheme using smart cards. Later, Yang and Wang pointed out that Wu and Chieu's scheme is vulnerable to the password guessing and forgery attacks. Recently, Lee et al. proposed an improved authentication scheme and claimed that their scheme is secure against forgery attack. However, in this paper, we illustrate that Lee et al.'s scheme is still vulnerable to the forgery attack. We also propose an enhancement of the scheme to resist such that attack. © 2010
