A Blockchain Based Access Control System for Internet of Things (IoT) Networks

Abstract

The rapid development and widespread application of IoT network systems, network security, in particular access control and data privacy, have become critical. Blockchain technology provides features such as decentralization, high reliability, and tampering prevention, which are advantages in solving the challenges of access control: audit ability, resource consumption, scalability, central authority, and trust. In this paper, we propose an ABAC access control system that can be applied to IoT networks. The proposed system utilizes Ethereum
