WBAN Security: study and implementation of a biological key based framework

Abstract

Translate Article

Wireless Body Area Network (WBAN) is becoming popular gradually and is showing better performance in health monitoring. In WBAN nodes are placed on or inside human body that collect information and send them to remote server wirelessly. Strict security is required to protect patient’s personal data. In this paper we made a detailed survey of the state-of-the art security works in WBAN. We propose a security framework by applying Advanced Encryption Standard (AES) technique using secret key derived from biological data of the patients as well as doctors for ensuring data confidentiality and authentication of users. We have implemented our proposed method in a cloud based environment to analyze end-to-end delay of patient data transmission using different keys derived from different biological information of users. Simulation setup and experimental results are given for detailed view and better understanding of our work.
