Device authentication mechanism for IoT enabled healthcare system

Internet of things (IoT) is the prelude to new technological innovation. It expands with different applications such as smart home, smart city, smart grids, smart car, smart healthcare and smart retail. The application of IoT in Healthcare system brings high value for the elderly, victims of chronic disease and those who require constant supervision. But there are many security issues in such application. Moreover, the medical devices used in the IoT enabled Healthcare System are resource constrained devices. So, this paper proposes a novel mechanism for authenticating such resource constrained medical devices. New algorithm for secure authentication and key agreement of the medical devices is also presented. This mechanism is resistance against various security attacks such as eavesdropping, man-in-the-middle and Denial of Service attacks. Formal security analysis and the comparative study presented in this paper have proved that the proposed mechanism has many security features and highly secure among the already existing authentication mechanisms.
