Revolutionizing Access Control in IoT Systems through Blockchain Technology

Abstract

The widespread adoption of the Internet of Things (IoT) has raised significant concerns regarding security and privacy. Among these concerns, access control stands out as a matter of paramount importance, generating substantial interest and discourse. Centralized systems, due to their reliance on external sources, often face challenges related to scalability and availability, which can lead to performance issues. This paper introduces an efficient, decentralized, and innovative approach to implementing secure access control systems within IoT frameworks. The proposed solution leverages a multi-agent system integrated with blockchain technology. The central focus of this methodology revolves around the deployment of Blockchain Managers to ensure the security of IoT access control and facilitate secure communication between neighboring IoT devices. An added advantage of this system lies in its establishment of a secure linkage among fog nodes, cloud servers, and IoT devices.
