Secure Elgamal Based Authentication Scheme for Cloud Assisted IOT Based Wireless Body Area Network

Now-a-days ireless Body Area Network (WBAN) is considered to be new era technique in which patient’s health record are monitored remotely by using wearable sensors from anywhere in the world. In such high-level communication, there is need of security services are required to protect the data being used by healthcare professionals and patients from intruders or attackers. Therefore, many researchers are showing their keen interest for security enhancement of WBAN architecture for secure communication. In this dissertation work, different security and privacy techniques are reviewed and analysed WBAN/IoT challenges as well their limitations based on the latest standards and publications. This research also covers the state-of-art security measures and research in WBAN. This research presents an ElGamal cryptosystem and biometric information authentication scheme for WBAN/IOT applications. This work observed that most of the authentication protocols using hash function and ElGamal cryptosystem for cloud-based applications are affected by security attacks and are unable to hide the actual identities of the end users during login session. Therefore, this work has introduced a secure biometric ElGamal-based authentication as well as data sharing schemes. The result analysis shows that the proposed work is better with respect to existing work with respect to execution time and cost as well as security level.
