New robust biometrics-based mutual authentication scheme with key agreement using elliptic curve cryptography

Abstract

In this work, we demonstrate that Chaudhry et al.’s recent biometrics-based three factor authentication scheme is vulnerable to the denial of service attack, and it also fails to provide perfect forward secrecy because it only uses the lightweight symmetric key primitives to ensure security. To enhance the information security, this article presents a new robust biometrics-based mutual authentication scheme using elliptic curve cryptography for client-server architecture based applications in mobile environment. The proposed scheme supports session key agreement and flawless mutual authentication of participants, which is proved under the BAN logic. Moreover, the proposed scheme provides prefect security attributes and resists all known attacks, and it has perfect performance in communication cost. Thereby, the proposed scheme is more suitable for client-server architecture based applications.
