Blockchain-Enabled Secure Data Sharing and Communication in IoT Networks

Abstract

The system includes sharing and controlling access to data among Internet of Things devices using blockchain technology. The proposed system addresses trust and challenges in authentication faced in IoT networks. Its objectives encompass establishing authentication, authorization and trust for sharing data over the network. To efficiently manage access control, the system employs smart contracts with Access Control Contract. The ACC governs the access control overall, while the RC verifies the identity of users within the system, and the JC enforces a behavior judgment method to detect any user misbehavior.
