Sharing Mechanism of Intelligent Vehicles Trust Points based on Blockchain for Vehicular Networks

Nowadays, there exists strong need to enable the Intelligent Vehicle (IV) communication for applications such as safety messaging, traffic monitoring and many other internet access purposes. In this work, we have introduced an Intelligent Vehicle Trust Points (IVTPs) sharing mechanism between vehicle to vehicle, vehicle to infrastructure and vehicle to roadside units. Existing models have already embeded Blockchain (BC), which is valuable for many purposes like security in different data transmission circumstances. However, our proposed scheme uses this BC feature along with IVTPs to ensure the trustworthiness in the communication environment. Performance of our proposed system is evaluated on the basis of IVs' processing time, which are totally based on IVTPs. Our proposed system is efficient as compared to existing one which handles less number of vehicles at intersection point where IVTPs are shared between moving vehicles in a scalable architecture.
