Wireless Body Area Network using Cryptography

Abstract

Network security has been great concern with recent technical advancement in wireless communication. And for that, a secured system is to be developed to provide data security over wireless transmission. This paper presents wireless body area network (WBAN) with cryptographic AES algorithm which monitors patient biomedical parameters based on sensors, Arduino and ZigBee. WBAN provides real-time measurements of patients health based on biomedical sensor. AES cryptographic algorithm is implemented for secure communication over wireless network by encryption and decryption of physiological parameters. Implementation of algorithm using Arduino has been communicated by ZigBee network to provide security to the encrypted data (cipher text) on medium cost devices. This ensures security of data for medical rehabilitation and monitoring of patients. The main purpose of this paper is to help a physician to treat patients during emergency by monitoring patients round the clock (24*7). This paper is helpful for elderly and disabled people with no assistance to measure and send the results to the doctor immediately.
