Arthur David, Francisca Nonyelum Ogwueleka · IntechOpen eBooks · 2025
Cyber-physical systems (CPS) are extensively used in overseeing the critical infrastructure of diverse domains such as medical healthcare, energy, and power. These applications typically receive input data from sensors, assess the current state of the system, and subsequently, make pivotal decisions for the automatic control of the underlying infrastructure. Consequently, safeguarding the security and integrity of the system state data becomes imperative to guarantee the secure and reliable operation of CPS. Therefore, the need to establish a stringent and dependable access control mechanism for data integrity within cyber-physical systems is imperative to ensure the effective implementation of modern functionalities. This paper addresses the intricacies of designing a robust access control system for cyber-physical systems. Leveraging blockchain technology, we introduce a practical framework and demonstrate how it will contribute to establishing a secure, dependable, and controlled system for data access with integrity. The central concept advanced by this research involves the meticulous management of access rights and the preservation of privacy through the application of blockchain strategies. The analytical findings underscore a high level of protection, decentralization, and reliability inherent in the proposed solution, capitalizing on the advantages offered by blockchain.
