Remote user authentication using smart cards is a good solution for many e-based applications. Smart card implementation ensures secure communications. Several schemes using timestamp for remote authentication have already been proposed. However these are vulnerable to certain types of forgery attack. Yang-Wang-Chang proposed an improved timestamp associated password authentication scheme based on Yang-Shieh, who had earlier proposed timestamp-based remote authentication scheme using smart cards. In this paper, the authors propose an efficient password authentication scheme with smart card applying RSA. The proposed scheme withstands most of the attacks with minimum computational cost.
