A Trust-Based Framework for IoT Device Management Using Blockchain Technology

Abstract

With the increasing use of Internet of Things (IoT) devices, ensuring their security and privacy has become crucial. Due to its decentralized and immutable nature, blockchain technology has emerged as a potential solution for effective device management. This study proposes a trust-based framework for managing IoT devices using blockchain techniques. The framework utilizes a blockchain-based decentralized trust model and employs a consensus mechanism to ensure system integrity and security. The feasibility and effectiveness of the proposed approach are demonstrated through simulation experiments. The framework achieves a trust score accuracy of over 90%, 30% higher than the best-performing approach in previous studies. The consensus mechanism implemented in the framework also reduces the probability of a security breach by 50% compared to the most secure system in prior research. This study shows that the proposed trust-based framework is a promising solution for managing IoT devices using blockchain technology, offering significant improvements over existing approaches.
