A Secure Three-Party Authentication Protocol for Wireless Body Area Networks

Abstract

In this era, the size of devices are decreasing and their capabilities are increasing, this leads to the development of portable and compact devices for communication around human bodies. Among them, some are implantable and some are wearable for a medical cause. These devices together form a network for communication called as Wireless Body Area Network (WBAN). Wireless Body Area Network 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 work, we propose an enhanced three-party authentication protocol using Elliptic Curve Cryptography (ECC) for WBAN. In our protocol, we are using a two-hop star extended topology based on WBAN standard. The results of BAN Logic and AVISPA tool provide the security proofs of the proposed protocol. Moreover, the implementation results prove the efficiency of our proposed protocol.
