In 2002, Yeh, Shen, and Hwang proposed a one-time password authentication scheme using smart cards. However, Tsuji et al. and Ku et al. showed that it is vulnerable to the stolen verifier attack. Therefore, this paper proposes an improved one-time password authentication scheme, which not only keeps the security of the scheme of Yeh-Shen-Hwang but also can withstand the stolen verifier attack.
