Blockchain Solutions for Enhancing Security and Privacy in Industrial IoT

The Industrial Internet of Things (IIoT) has revolutionized smart manufacturing by enhancing automation, operational efficiency, and data-driven decision-making. However, the interconnected nature of IIoT devices raises significant concerns about data privacy and security. This paper explores the use of blockchain technology to address these challenges, focusing on data integrity, access control, and traceability. The paper proposes a blockchain-based framework that leverages decentralized security, smart contracts, and edge computing to mitigate vulnerabilities such as unauthorized access and data manipulation. The framework is evaluated for practicality, scalability, and constraints within IIoT environments. Additionally, the paper discusses integrating complementary security mechanisms, such as Zero-Trust architecture and AI-driven anomaly detection, to provide a comprehensive cybersecurity solution for IIoT.
