Two-Factor User Authentication with Key Agreement Scheme Based on Elliptic Curve Cryptosystem

الملخص EN

A password authentication scheme using smart card is called two-factor authentication scheme.

Two-factor authentication scheme is the most accepted and commonly used mechanism that provides the authorized users a secure and efficient method for accessing resources over insecure communication channel.

Up to now, various two-factor user authentication schemes have been proposed.

However, most of them are vulnerable to smart card loss attack, offline password guessing attack, impersonation attack, and so on.

In this paper, we design a password remote user authentication with key agreement scheme using elliptic curve cryptosystem.

Security analysis shows that the proposed scheme has high level of security.

Moreover, the proposed scheme is more practical and secure in contrast to some related schemes.
