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

Preeti Chandrakar, Hari Om

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.

Privacy-Enhancing Authenticated Key Agreement Protocols Based on Elliptic Curve Cryptosystem

Hong Lei

Authenticated key agreement protocol is designed to provide pair of parties communicating over an insecure network with a secure session key.However,most of the existing authenticated key agreement protocols are not designed for protecting privacy.We emphasize user's privacy properties in network services,in particular we stress anonymity and deniability.We specify the desired security properties of privacy-enhancing authentication key agreement protocols,i.e.mutual authentication,key control,key confirmation,session-key confidentiality,known-key security,forward secrecy,anonymity of user,forward anonymity of user,unlinkability,deniability.Based on elliptic curve cryptosystem we also propose a protocol which satisfies all the desired security properties.
