摘要：In 2004, Das et. al proposed a Dynamic ID based remote authentication scheme to authenticate the users while preserving the user��s anonymity .Chein et. al. pointed out that Das et. al scheme fails to protect the user��s anonymity and proposed a new scheme to conquer the weakness in 2005. In this paper, we show that Chein et al scheme is insecure against Insider attack and Man-in-middle attack. An improved scheme is proposed that overcomes the security risk.
