The Study of Password Authentication System Based on Elliptic Curve Cryptosystem
Aiming at the security problems of the password authentication systems in existence, this paper studies the elliptic curve cryptosystem basic principle, and then proposes a new password authentication scheme based on the elliptic curve cryptosystem. The particular implementation of this scheme is presented. And the security is analyzed finally. In this scheme, users passwords are difficult to be explained in the process of storage and transmission. Authentication information keep dynamic, so replay attack can be prevented effectively. In addition, veritable users can detect the illegal uses who misappropriate the passwords so information divulges or resources embezzlement can be refrained. This scheme is secure, effective ,easy to implement and hopeful for application.
