Abstract
Social Internet of Things (social IoT) is a paradigm that integrates the social network concepts with IoT in which objects in the network are able to establish social relationships with each other. In these networks, to preserve privacy and security, the access to IoT resources can be handled based on social trust evaluation of the devices. This paper examines a blockchain-based trust management system for edge-enhanced IoT that uses social information of the system to strengthen the trust evaluation. Moreover, this system leverages information entropy to enhance security. We also developed a proof of concept system to show that the proposed solution can effectively assess trust factors in social IoT.
