Road safety has been drawing increasing public attention, and there has been extensive effort in both industry and academia to mitigate the impact of traffic accidents. Recent advances in wireless technology bring promising new ways to facilitate road safety and traffic management, in which each vehicle, equipped with wireless communication devices [referred to as onboard units (OBUs)], is allowed to communicate with vehicles, other as well as with roadside units (RSUs), which are located at critical sections of the road, such as traffic lights and stop signs. With OBUs and RSUs, a self-organized network called a vehicular ad hoc network
(VANET) can be formed. Recently, this has emerged as a promising approach toward increasing road safety and efficiency, as well as improving driving experience. These goals will be accomplished through a wide variety of vehicle applications enabled by communication between vehicles, such as emergency braking warning. While society
experiences tremendous benefits from adopting the new technologies, we also continue to face challenges; the biggest challenge is always how to address security and privacy issues that may be caused by the adoption of a new technology. The attractive features of VANETs will inevitably incur higher risks for abuse, if we do not take security and privacy issues into consideration before the wide deployment of such networks networks (MANETs), a VANET has many unique features and applications. First, the connectivity among nodes (vehicles and RSUs) can often be highly transient and a one-time event; two vehicles may remain within their transmission ranges, or within a
few wireless hops, for only a very limited period of time
As a result, vehicular network topology is highly dynamic. Further, a VANET is a huge network, which can potentially consist of millions of nodes (on-road vehicles and RSUs). Such size makes it very challenging to guarantee security and privacy in VANETs, particularly regarding message authenticity and integrity, as well as protecting user-related privacy information, such as the driver’s name and the car’s license plate, model, and traveling route
