A secure two-factor mutual authentication and session key agreement protocol using Elliptic curve cryptography

Abstract

In this paper, we propose a secure two-factor remote user authentication protocol using Elliptic curve cryptography. The proposed protocol provides the mutual authentication of participants, session key agreement and user anonymity. The security of our proposed protocol is based on one way hash function and elliptic curve cryptosystem and it is secure against all relevant security attacks. Compared with other relevant protocol, the security analysis and performance evaluation show that our proposed protocol can provide high level of security with less communication and computation cost. In addition, the BAN logic is applied to demonstrate the validity of the proposed protocol.
