A proposal of a distributed access control over Fog computing: the ITS use case

Internet of Things (IoT) raises many security challenges in relation with the different applications that can be deployed over these environments. IoT access control systems must respond to the new IoT requirements such as scalability, dynamicity, real-time interaction and resources constraint. The goal of this paper is to propose an approach based on Fog and Distributed Hash Table (DHT) toward access control for the Internet of Things. To evaluate the performances of our access solution, we used NS-3 and SUMO. The preliminary obtained results show acceptable overhead for the considered Intelligent Transport System (ITS) scenario.
