Abstract: In 2003, Lin et al. proposed an improvement on the Optimal Strong-Password Authentication (OSPA) scheme to make the scheme withstand the stolen-verifier attack, using smart card. However, Ku et al. showed that Lin et al.|s scheme is vulnerable to the replay and the denial of service attack. In 2004, Chen et al. proposed a secure SAS-like password authentication schemes. Their schemes can protect a system against replay and denial-of-service attacks. In this paper, we propose two efficient and secure password authentication schemes which are able to withstand replay and denial-of-service attacks. The proposed schemes are more efficient than Chen et al.|s schemes in computation costs. Moreover, the proposed schemes can be implemented on most of target low-power devices such as smart cards and low-power Personal Digital Assistants in wireless networks.
