An Enhanced Authentication Scheme for Internet of Things Based E-Healthcare System

Abstract

Security is a major challenge in modern IoT based healthcare monitoring systems. It provides many benefits such as critical patient monitoring, remote diagnosis at anytime, anywhere. Hence, security of this data is essential when the healthcare professionals access it. Also, while storing the patients record; it must be kept safe from misuse and modification of data as other devices can easily track it. To prevent this type of threats, we have proposed a mutual authentication protocol to enhance health care security and to resist vulnerable attacks. The proposed scheme used Challenge response protocol for the authentication purpose and the Diffie-Hellman key exchange protocol is used for generation of the session key generation. The security analysis of the proposed scheme shows that the scheme is more secure and resist all the major attacks as compared to other schemes. The Formal verification of this schema also ensures that it resists most probable attacks in this system. The result of the proposed authentication scheme shows that it has low computational and communicational load.
