In 2013, Lee-Lie proposed secure smart card based authentication scheme of Zhu’s authentication for TMIS which is secure against the various attacks and efficient password change. In this paper, we discuss the security of Lee-Lie’s smart card-based authentication scheme, and we have shown that Lee-Lie’s authentication scheme is still insecure against the various attacks. Also, we proposed the improved scheme to overcome these security problems of Lee-Lie’s authentication scheme, even if the secret information stored in the smart card is revealed. As a result, we can see that the improved smart card based user authentication scheme for TMIS is secure against the insider attack, the password guessing attack, the user impersonation attack, the server masquerading attack, the session key generation attack and provides mutual authentication between the user and the telecare system.
