Security and privacy via optimised blockchain

Abstract

Security of IoT devices and applications can be improved by using the emerging Blockchain Technology which uses decentralised interaction and scalable architectures with security and distributed trust. In this work a review of Lightweight scalable Blockchain is proposed for security and privacy of IoT devices. An IoT scenario of smart home is used for illustrative purposes but this proposed architecture is wellsuited for diverse IoT applications. Effectiveness of this architecture is analysed using common threat models which provides an appropriate assessment for security and privacy implementation for smart home.
