Cryptanalysis and Improvement of Jiang et al.'s Smart Card Based Remote User Authentication Scheme

Dheerendra Mishra, Ankita Chaturvedi, Sourav Mukhopadhyay

The smart card based authentication protocols try to ensure secure and authorized communication between remote entities. In 2012, Wei et al. presented an improvement of Wu et al.'s two-factor authentication scheme for TMIS which is proven vulnerable to off-line password guessing attack by Zhu. Zhu also proposed a modified scheme to overcome with weakness of Wei et al.'s scheme, although Lee and Liu showed the failure of his scheme to resist parallel session attacks. Moreover, Lee and Liu introduced an improved scheme. We analyze Wei et al.'s, Zhu's and Lee and Liu's schemes and identify that none of the schemes resist on-line password guessing attack. Moreover, these schemes do not present efficient login and password chance phase. We also show that how inefficient password change phase causes denial of service attack. Further, we propose an improved password based remote user authentication scheme with the aim to eliminate all the drawbacks of previously presented schemes.
