Data Communication Protocol using Elliptic Curve Cryptography for Wireless Body Area Network

Abstract

Wireless Body Area Network plays a major role in patient health monitoring, and controlling is the best method in the present generation. Nowadays, especially the patient’s status information plays a vital role and must also be securely covered. One of the major challenges is to provide secure transmission between nodes. This paper recommends that the confidentiality of patients’ medical data be protected by implementing two concepts called the Diffie-Hellman key generation method for different key sizes and Elliptic Curve Cryptography (ECC). A biometric authentication system is also proposed where the biometric images are used as secret keys to authenticate legitimate users and data users like doctors and patients. This system implements an asymmetric encryption algorithm that is more effective and produces a better outcome. The focal point is to produce a better performance on the wireless domain using ECC.
