Efficient Integrated Blockchain-based Authentication System for IoT

Abstract

In day-to-day life, the Internet of Things(IoT) plays a major role. Without the human interface, data is stored and shared in IoT.  These entities are also implemented in open environments to provide a smarter and easier way of living such as smart homes, smart cities, etc. Because of this complete autonomy, these entities need to be acknowledged and authenticated with each other and therefore ensure the validity of their data exchanged. Otherwise, malicious users and malicious use will target them. Because of the size and features of IoT an efficient centralized authentication system cannot be created. In this paper, the IoT devices have an efficient decentralized authentication and access control framework which applies to a smart hospital.
