Vehicular ad hoc network (VANET) is an emerging new communication technology which has attracted a lot of research attention from academic community and industry. For many applications in VANETs, information has to be transmitted through multiple hops before it reaches its destination that makes it a subject to various security attacks and privacy breaches. Thus, security and privacy issues could limit its adaption by the public community
In this study, we propose and evaluate social based trustworthy data forwarding scheme for VANET. First, by using social network analysis techniques, we provide a framework to strategically deploy Road-Side Units (RSUs) infrastructure in order to improve reliability, efficiency, and high packet delivery for VANET. It is based on multiple social centrality assessments of street network which help in placing RSUs at high social intersections. This social placement of RSUs will dramatically improve data dissemination as the opportunity of contacting vehicles increase while costs of RSU deployment can be kept under control. Second, we propose a secure and privacy-preserving message forwarding protocol, which utilizes RSUs to forward messages between vehicles. The protocol takes advantage of high performance capability of RSUs to store and forward messages to their destinations, where these RSUs utilize re-encryption technique to form a mix network to provide adequate privacy for senders and receivers. Then detailed analysis in terms of security, message overhead, delivery ratio, and average delay are performed to evaluate the efficiency and effectiveness of our proposed scheme. Lastly, we tackled the security and privacy challenges existing in social-aware data diffusion by proposing an efficient vehicle social evaluation (EVSE) scheme. Our scheme enables each vehicle to show its authentic social evaluation to others while not disclosing its past location information. As a result, it can meet the prerequisites for the success of social aware data diffusion in VANETs
