Cryptanalysis and Improvement on Robust Three-Factor Remote User Authentication Scheme with Key Agreement for Multimedia System

Younsung Choi and Dongho Won

Abstract: A three-factor authentication combines biometrics information with user password and smart card to provide security-enhanced user authentication. An proposed user authentication scheme improved Dasís scheme. But Anís scheme is not secure against denial of service attack in login phase, forgery attack. Li et al. pointed out them and proposed three-factor remote user authentication scheme with key agreement. However, Li et alís scheme still has some security problem. In this paper, we present a cryptanalysis and improvement of Li et al.ís remote user authentication scheme.
