Abstract :
In 2000, Hwang and Li proposed a new remote user authentication scheme using smart cards. Chan and Chang showed that the masquerade attack is successful on this scheme. Recently Shen, Lin and Hwang pointed out a different type of attack on this scheme and presented a modified scheme to remove these defects. In this paper we present a new scheme which also overcomes these attacks. In this scheme previously generated passwords are secure even if the secret key of the system is leaked or is stolen.
