Abstract

In 2006, Manik et al. proposed a novel remote user authentication scheme using bilinear pairings. Chou et al. identified a weakness in this scheme and made improvements. In addition, Thulasi et al. noted that both Manik et al.'s and Chou et al.'s schemes are vulnerable to forgery and replay attacks. In this paper, we analyze the previous schemes based on a timestamp and provide further comments together with an improved scheme using a nonce.
