A Password Authentication and Update Scheme Based on Elliptic Curve Cryptography

Secured password authentication and update of passwords are two essential requirements for remote login over unreliable networks. In this paper, the design problem of a newly proposed password authentication and update scheme based on Elliptic Curve Cryptography (ECC) is discussed. Then the authors propose a new ECC-based password authentication and update scheme that can resist replay attack, offline password guessing attack, etc., and satisfy perfect forward secrecy, and the detailed security analysis of the proposed scheme against the attacks has been given.
