Abstract : Distributed Cyber-Physical Systems (DCPS) are increasingly vulnerable to security threats due to their complex, interconnected nature. Traditional security mechanisms struggle to ensure trust, integrity, and resilience against malicious attacks and system failures. Blockchain technology, with its decentralized and immutable ledger, offers a promising solution to enhance security in DCPS. This paper explores the integration of blockchain with Practical Byzantine Fault Tolerance (BFT) to address security challenges in DCPS. PBFT consensus mechanisms enable systems to function reliably even in the presence of malicious nodes, ensuring fault tolerance and data integrity. By leveraging blockchain and BFT, this approach mitigates single points of failure, enhances trust among distributed components, and secures communication against cyber threats. This paper presents a detailed analysis of blockchain-based PBFT models for DCPS security, evaluating their performance, scalability, and resilience. The findings demonstrate that integrating blockchain with PBFT enhances system reliability, improves data authenticity, and strengthens overall cybersecurity in DCPS environments.
