A secure three-party authentication protocol for wireless body area networks

Wireless Body Area Network (WBAN) is one of the most rapidly growing technologies in the field of healthcare. However, providing a secure communication system over WBAN is a challenging task due to the sensitive data exchanged in resource-constrained WBAN. In this paper, we propose an efficient three-party authentication protocol for WBAN using Elliptic Curve Cryptography (ECC). We are using two-hop star network topology based on WBAN standard. The analysis results of BAN Logic and AVIS PA tool provide the security proofs of the proposed protocol. Moreover, the implementation results prove the efficiency of our proposed protocol.
