Summary

Cyber-Physical System (CPS) combines physical objects (e.g., smartphones) or systems (e.g., autonomous TV) with integrated computing and storage capabilities. CPS is an interconnected network of systems and objects through which it exchanges information with each other. CPS applications are widespread some of them include smart grids, E-health, enterprise management, logistics, industrial production, and management processes. In today’s scenario, CPS acts as a disruptive technique that replaces traditional power systems with advanced CPS infrastructures. This ongoing transmission from centralized to distributed Cyber-Physical systems invokes robust, secure and efficient infrastructures. The critical nature of CPS with a high level of heterogeneity, complexity, and resource-constrained properties increases the risk of secure fault-tolerant resilience computer system. On the other hand, the prompt advancement of IoT systems deeply penetrates several cyberattacks which, often affects millions of lives. Since every computerized data highly influence the decision-making process, the protection of data integrity, security, and authenticity have become the essential factors.

A recent distributed computing paradigm called blockchain provides a promising solution for modern CPS applications. Blockchain forms an underpinning technique for CPS that offers fault-tolerant, reliable, secure, and efficient computing infrastructure. It is a distributed ledger provides reliable infrastructures through various features such as cryptography, smart contract, and consensus algorithms. In a blockchain environment, the information is actively verified across all the nodes in the network using a consensus algorithm and then replicated. It makes use of distributed storage mechanisms, and every node across the network has a copy of the data. Blockchain and its inherent combination of consensus algorithms, distributed storage with advanced security protocols provide the most effective solution for modern CPS applications. However, the computationally expensive nature of the blockchain with higher bandwidth overhead and delays remains to be the most challenging factor when applied towards CPS. Thus the formulation of an efficient blockchain algorithm can protect the CPS systems for vulnerable security risks and provide a new direction to the research of CPS applications. At present, enhancing the performance of CPS using blockchain has become an active area of research enabling researchers from academic and industrial backgrounds to get deeply involved in finding efficient solutions for secure CPS systems.
