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
