A Distributed Trust Management model for the Internet of Things (DTM-IoT)

The Internet of Things (IoT) is a paradigm that facilitates autonomous communications among various IoT devices with minimal human intervention. This raises many security challenges, which are critical and must be addressed to allow for the wide deployment of IoT. Trust must be provisioned among the various heterogeneous IoT devices. In this paper, a distributed trust management model is proposed. The model offers solutions to trust management and negotiations in the IoT. It is inspired by clustering techniques that are adopted in WSNs. After introducing the structural design and the main components of the trust model, we demonstrate how our new approach supports trust negotiations and management in the IoT.
