Secure and Privacy Preserving Navigation in VANET

In todays communication world technologies reformed humans lifestyles by providing the best effective and beneficial personal and public communication applications with the help of internet services. Recently, in vehicle manufacturers and telecommunication industries gear up to equip each vehicles and cars with the facility that allows the vehicle to vehicle communication with each other as well as with the RSU, which is located near the road, such as at every traffic signal or any important location which exist on fixed distance, in order to good driving experience, facilitate secure driving, and enhance people safety and security. In this research paper, we propose a navigation method that utilizes the road information collected by a vehicular ad hoc network (VANET) which helps to guide the drivers to reach desired destinations in a real-time. The proposed scheme provides the advantage of get real-time road conditions to analyse a better route and simultaneously, the providing information source can be properly authenticated. To protect the real identity of the drivers, the submitted query (destination) and the driver or user who submit the query are must guaranteed to be not linkable to any party including the trusted authority (CA). We make use of the idea of anonymous credential (dummy and not original) to achieve this goal. In addition to message authentication and privacy preserving, our scheme also provide other necessary security requirements. Using the real maps scenario of New York and California, we performed a simulation study on our proposed scheme showing that it is effective and efficient in terms of processing delay and providing proper routes of shorter traveling time.
