TRFIoT: Trust and Reputation Model for Fog-based IoT

摘要

Where IoT and Cloud Computing are revolutionizing today's ecosystem, they also cause alarming security and privacy issues. As a continuum of devices and objects are interconnected with each other in order to share data and information. It is really important to evaluate the trustworthiness of these devices/objects, whether they are trustworthy or malicious. In this work, we propose a novel Trust and Reputation (TR) based model to outsource malicious users in a Fog-based IoT (FIoT). In our model, we used a multi-source trust evaluation by taking into account of the reputation of participating nodes. We use the feedback system to make the trust system reliable and trustworthy. We evaluate our model with simulations and the result shows the effectiveness of TRFIoT.
