摘要: Recently, a novel remote user authentication scheme using bilinear pairings was proposed. The is insecure, however, against forgery attack and replay attack. In this paper we propose new design for the properties of pairings, elliptic curve ElGamal encryption decryption scheme. By employing EC decryption, attacks can be blocked. Moreover, strong password change method, which overcomes changing weakness, provided. Finally analyze security performance our design.
