Vehicular communication technologies have been envisioned as a promising approach for improving road safety, enhancing driving experience, and improving traffic management. In the future, cars on our roads will be equipped with vehicle-to-vehicle (V2V) communication technology enabling them to communicate with each other and forming a large self-organized ad hoc network. These networks are called vehicular ad hoc network (VANET). In this talk, we first identify some security and privacy challenges in VANETs. Then, we look into how to integrate social links into VANETs. Specifically, we study social behavior and interaction in VANETs and then propose a social-aware, secure and privacy-preserving packet forwarding scheme. With the proposed scheme, Roadside Units (RSUs) deployed along the roadside can assist in packet forwarding to achieve highly reliable transmissions, which is considered critical for many vehicle applications. In specific, we heuristically define how to evaluate each traffic intersection’s social degree in a VANET. Based on the social degree information, we then strategically place RSUs at some high-social intersections. As a result, these RSUs can provide tremendous assistance in temporarily storing packets and helping packet forwarding in order to achieve high delivery ratio in a cost-efficient way. Furthermore, these RSUs can form a mix network to shuffle messages transmitted over vehicular network. As a result, security and privacy of vehicular communications can be guaranteed.
