A Provably Secure Anonymous Biometrics-Based Authentication Scheme for Wireless Sensor Networks Using Chaotic Map

The rapid growth of wireless sensor networks (WSNs) has opened new doors to realize remote monitoring in various areas. However, designing authentication protocol for resource-constrained WSNs is a challenging task. Recently, Aghili et al. introduced an efficient three-factor authentication scheme for WSNs using hash function, and argued that the scheme is immune to known attacks. However, we discover that their scheme suffers from a few serious weaknesses, such as session key disclosure attack, desynchronization attack, sensor node impersonation attack, and session-specific temporary information attack, and does not provide forward secrecy. In order to overcome the deficiency of this scheme, we propose an enhanced biometric-based authentication scheme for WSNs using Chebyshev chaotic map. We demonstrate that the proposed scheme is provably secure in the random oracle model. Furthermore, Burrows–Abadi–Needham logic analysis shows that the proposed scheme achieves mutual authentication and session key agreement. The informal analysis demonstrates that the proposed scheme is resistant to various attacks and has desirable attributes, such as forward secrecy and three-factor secrecy. Finally, the security and performance comparison show that the proposed scheme is more practical.
