Implementation of biological key based security technique in wireless body area networks

Abstract

These days, due to advancements in the technology, security has become the main concern in almost in every field. WBAN has appeared as a popular technologyfor controlling and monitoring the health of the patients. The information of patient’s the health status is very crucial and sensitive which must be protected from any illegitimate access. In this paper, a framework is proposed for the security and privacy of medical data of patients by applying Elliptic Curve Cryptography and Diffie-Hellman key generation method for different key sizes. Biometric authentication is used in our system. The biometric images are used as secret keys which are used by the doctors to attain the patient’s information. The proposed system replaces the symmetric encryption algorithms used in existing system and offers effective and better results.
