BLOCKCHAIN BASED TRUST MANAGEMENT FRAMEWORK FOR IoT DEVICES

Abstract

This project explores a novel approach to trust management for IoT devices within the context of e-health applications. IoT devices contribute trust parameters to a centralized server, which aggregates data and computes context-based trust using Ethereum smart contracts. The trust scores are securely recorded on the blockchain, ensuring transparency and immutability. The system, developed within the Hardhat environment, encompasses a frontend where authenticated users can access and visualize the calculated trust scores for each IoT device. This approach not only enhances user privacy but also fortifies the security of the trust management system. The research delves into the challenges and considerations associated with implementing this blockchain-based trust management framework. By providing an overview of the architecture and authentication mechanisms, the study aims to contribute to the broader understanding of secure and transparent trust management systems for IoT devices in E-Health applications. This project centers around a dynamic ecosystem of IoT devices contributing trust parameters to a server, which aggregates data from all devices. Subsequently, context-based trust is computed through an Ethereum blockchain smart contract. The integration employs a React-based frontend where users, authenticated prior to access, can visualize and interact with the calculated trust scores for each IoT device. This innovative solution offers a comprehensive and secure framework for assessing and visualizing the trustworthiness of IoT devices in real-time, paving the way for more transparent and accountable interactions in IoT-driven environments within e-health applications.
