Abstract
Recently, Chung, Lee, and Won [1] proposed an improved authentication scheme with anonymity which remedies security faults showed by Youn, Park, and Lim [2]. Their improved scheme guarantees anonymity, but does not provide unlinkability. In their scheme, it is possible for attackers to know particular sessions, that have already been occurred several times, are originated by one same user. In this paper, we propose an unlinkable authentication scheme with anonymity by modifying Chung et al.’s scheme. Our scheme provides not only anonymity and security as the previous scheme does, but also unlikability against malicious mobile users. Since proposed scheme still uses only low-cost functions, it is suitable for mobility networks.
