Cryptanalysis of Two Improved Password Authentication Schemes Using Smart Cards
Recently, Yang et al. improved Yang and Shieh's two password authentication schemes to withstand Sun and Yeh's forgery attacks. However, Kim et al. pointed out that Yang et al.'s improvements still cannot withstand forgery attacks. At the same time, Kim et al. proposed improved methods. In this paper, we shall show that Kim et al.'s improvements also cannot resist the forgery attacks.
