Trust Management Technique Using Blockchain in Smart Building

Abstract

Security is a big challenge for developing and implementing IoT in smart building situations. In this context, our goal is to create a secure blockchain-based trust management system. To do so we take advantage of the security features that blockchain technology provides in terms of reliability, traceability, and data integrity. We design and implement a blockchain-based trust strategy that collects trust evidence, assigns each device a trust score, and securely stores and shares them with other devices in the network by integrating them into blockchain exchanges. According to the findings of our performance evaluation, our concept includes security features such as tamper-proofing and assault resistance, reliability, and easy implementation for IoT environments and applications.
