Internet of Things (IoT)-Cyber Physical Systems (CPS)- An exploratory survey on the security of IoT-CPS framework using blockchain technologies

Abstract

In recent decades, the advent of Internet of Things (IoT) and Cyber Physical Systems (CPS) are skyrocketing where millions of devices are connected together for seamless computing and processing high-end applications. Well-designed IoT-CPS provides enhanced energy efficiency, safety in smart grids, smart homes and intelligent transport systems. Though the advancements making these systems as a technological trend, the security and privacy issues with these systems are still challenging. To address those challenges, blockchain technology is adopted for secure data transfer in heterogenous IoT-CPS and peer-peer networking systems. In this survey an exploratory approach on the security of IoT-CPS framework using blockchain technologies is described. This survey also encompasses underlying concepts in blockchain and IoT-CPS applications using blockchain. Furthermore, the various security issues and challenges in applying blockchain for IoT-CPS are also identified.
