Abstract:
The growing integration of Internet of Things (IoT) into industrial environments highlights the need for adequate security and privacy maintenance. While traditional access control methods fall short in addressing the rising challenges of such environments, the combination of capability-based access control (CapBAC) models with blockchain technology emerges as a promising alternative. In this paper, we conduct a comprehensive analysis and comparison of approaches that integrate these two concepts. The evaluation of each approach is based on twelve criteria, including scalability, performance, efficiency, latency, throughput, degree of decentralization, consensus mechanism, smart contracts adoption, complexity, interoperability, security guarantees, and privacy. The aim of our analysis is to examine whether the combination of CapBAC and Blockchain brings a new era of secure industrial IoT (IIoT) operations. In order to identify the strengths and the areas for improvement, we provide f
our types of comparison to further assess these approaches based on IIoT requirements. Finally, we thoroughly discuss our findings, indicating directions for future research in order to enhance the adoption of such innovative mechanisms across broader industrial landscapes.
