Abstract

Recently, Das et al. proposed a dynamic ID-based remote user authentication scheme using smart cards. Liao et al. pointed out some weaknesses of Das et al.’s scheme, and presented an improved scheme. However, an impersonate attack on Liao et al.’s scheme is proposed, it proves that their scheme is also insecure. To overcome the weakness, the new scheme is presented. The advantage of the proposed scheme is that there are no secret numbers in the smart card, and can withstand all sorts of attacks.
