DESIGN OF AN EFFICIENT, SECURE AND LIGHTWEIGHT MUTUAL AUTHENTICATION SCHEME FOR WIRELESS BODY AREA NETWORKS

Abstract

Wireless Body Area Networks (WBANs) have emerged as a critical technology in healthcare for real-time monitoring of physiological data. (WBANs) enable continuous health monitoring through wearable and implantable sensors. However, due to the sensitive nature of medical data and the resource constraints of sensor nodes, designing secure and lightweight authentication protocols remains a major challenge. This paper presents a secure and lightweight authentication protocol designed specifically for WBAN environments.

The protocol ensures mutual authentication, confidentiality, integrity, anonymity, and forward secrecy while minimizing computational and communication overhead. Performance and security analyses demonstrate that the proposed protocol achieves an optimal balance between security and efficiency, making it suitable for practical WBAN deployments.
