Improvement of recently proposed Remote User Authentication Schemes
Guanfei Fang and Genxun huang
Abstract: Abstract. Recently Manik et al.  proposed a novel remote user authentication scheme using bilinear pairings. Chou et al.  identified a weakness in Manik et al.â€™s scheme and made an improvement. Thulasi et al.  show that both Manik et al.â€™s and Chou et al.â€™s schemes are insecure against forgery attack and replay attack. But Thulasi et al. do not propose a improvement. In this paper, we propose an improvement to over come the flaws.
