Abstract:Remote user authentication scheme is a mechanism which allows a server to authenticate a remote user over insecure channel. In 2006, Das et al proposed a remote user authentication scheme using bilinear pairings according to the merits of bilinear pairing on an elliptical curve. In 2009, Goriparthi et al pointed out that Das et al’s scheme is easily vulnerable to the replay attack and the forgery attack, and proposed an improved scheme.However,found out weaknesses of Goriparthi et al’s scheme against the insider attack, the denial of service attack, the server spooling attack and the existing clock synchronization problem. To overcome these weaknesses,proposed a novel authentication scheme for remote users based on bilinear pairing and nonce using smart cards. The security analysis shows that the proposed scheme not only enhances the security of the authentication system but also accomplishes mutual authentication safely between the user and the remote system. ......
