Abstract
Internet of Things (IoT) security is a fundamental challenge for the enterprises working behind the buildup of the IoT, and it is related applications. In today’s ara, with IoT, another buzzword is a blockchain-based cryptocurrency and other blockchain applications. Blockchain technology has proven itself one of the most secure existing technology in trust and privacy. This paper discusses IoT and blockchain technology fundamentals, followed by a discussion regarding numerous consensus models. We also discuss mathematical foundations used by blockchain technology, and it is followed by the proposed privacy-preserving technique for IoT devices with better device identity management using blockchain technology. This paper presents a novel solution for privacy preservation and identity allocation using secure identity management through public key-based cryptography-based blockchain. Though we consider smart home management and smart health management’s ecosystem for applicability discussion of the proposed scheme, the proposed system can be applied to any IoT application for better privacy preservation. Finally, we conclude with the discussion regarding the futuristic scope of the proposed system.//
