Vehicular Ad-Hoc Network (VANET) communication has recently become an increasingly popular research topic in the area of wireless networking as well as the automotive industries. The goal of VANET research is to develop a vehicular communication system to enable quick and costefficient distribution of data for the benefit of passengers safety and comfort. But location privacy in vanet is still an imperative issue. To overcome this privacy, a popular approach that is recommended in vanet is that vehicles periodically change their pseudonyms when they broadcast safety messages. An Effective pseudonym changing at proper location(e.g., a road intersection when the traffic light turns red or a free parking lot near a shopping mall) (PCP) strategy to achieve the provable location privacy. In addition, we use Bilinear Pairing for self-delegated key generation. Current threat model primarily considers that an adversary can track a vehicle that can utilize more character factors to track a vehicle and to explore new location-privacy-enhanced techniques under such a stronger threat model.
