DPS-IIoT: Non-interactive zero-knowledge proof-inspired access control towards information-centric Industrial Internet of Things

The advancements in 5G/6G communication technologies have enabled the rapid development and expanded application of the Industrial Internet of Things (IIoT). However, the limitations of traditional host-centric networks are becoming increasingly evident, especially in meeting the growing demands of the IIoT for higher data speeds, enhanced privacy protections, and improved resilience to disruptions. In this work, we present the ZK-CP-ABE algorithm, a novel security framework designed to enhance security and efficiency in distributing content within the IIoT. By integrating a non-interactive zero-knowledge proof (ZKP) protocol for user authentication and data validation into the existing Ciphertext-Policy Attribute-Based Encryption (CP-ABE), the ZK-CP-ABE algorithm substantially improves privacy protections while efficiently managing bandwidth usage. Furthermore, we propose the Distributed Publish-Subscribe Industrial Internet of Things (DPS-IIoT) system, which uses Hyperledger Fabric blockchain technology to deploy access policies and ensure the integrity of ZKP from tampering and cyber-attacks, thus enhancing the security and reliability of IIoT networks. To validate the effectiveness of our approach, extensive experiments were conducted, demonstrating that the proposed ZK-CP-ABE algorithm significantly reduces bandwidth consumption, while maintaining robust security against unauthorized access. Experimental evaluation shows that the ZK-CP-ABE algorithm and DPS-IIoT system significantly enhance bandwidth efficiency and overall throughput in IIoT environments.
