Sec-IoT: A Framework for Secured Decentralised IoT Using Blockchain-Based Technology

Abstract

Blockchain technology has been used recently as a secure method for authenticating digital information in many applications. Inspired by the success of the technology, we envision the potential of the blockchain for secured communication in a decentralised Internet of things (IoT). In this paper, we envisage a framework for a secured IoT and describe the infrastructure and mechanism of the entire system. Also, we provide solutions to overcome some of the limitations of blockchain technology including miner selection and reaching consensus, for a decentralised IoT by incorporating a learning-to-rank method for node selection. We also contemplate using hybrid consensus algorithm in the blockchain to detect faulty node and to improve the node convergence.
