CD-BISHAC: Cross-Domain Scheme for Blockchain-Based Industrial Internet of Things Security Hybrid Access Control

The Industrial Internet of Things (IIoT) is currently confronted with significant security challenges, including the complexities associated with cross-domain device permission management, the risks of privacy breaches during data transmission, and the vulnerabilities inherent in centralized security architectures to various forms of attack. Existing access control schemes are inadequate for addressing the dynamic and intricate nature of industrial environments, often falling short of meeting the IIoT system’s flexibility, security, and scalability requirements. This article introduces a novel hybrid access control scheme based on blockchain technology within a cross-domain context to tackle these issues. This approach synergizes the simplicity of role-based access control (RBAC) with the adaptability offered by attribute-based access control (ABAC) while harnessing blockchain’s decentralization, immutability, and transparency to bolster system security, autonomy, and capabilities for cross-domain management. We assessed this scheme’s effectiveness in defending against various threats through comprehensive security analysis. Furthermore, experimental results indicate that our proposed solution provides robust security guarantees and surpasses traditional approaches regarding efficiency and performance. Consequently, the scheme presented herein signifies a substantial innovation in IIoT security practices—offering a feasible and reliable solution tailored for complex cross-domain environments.
