Cryptanalysis of an Exquisite Mutual Authentication Scheme with Key Agreement Using Smart Card

He Debiao, Chen Jianhua, Hu Jin

Abstract: The weakness of an exquisite authentication scheme based on smart cards and passwords proposed by Liao et al. [C. H. Liao, H. C. Chen, and C. T. Wang, An Exquisite Mutual Authentication Scheme with Key Agreement Using Smart Card, Informatica, Vol. 33, No. 2, 2009, 125-132.] is analyzed. Five kinds of weakness are presented in different scenarios. The analyses show that Liao et al.ís scheme is insecure for practical application.
