A vehicular Ad-hoc network is an ad-hoc network of vehicles supported by fixed infrastructure. It is characterized by a highly dynamic topology with vehicles moving in a restricted road environment with different speeds. Vehicles are equipped with wireless communication devices known as On-Board Units (OBU) which enables them to communicate with other vehicles and Roadside Units. Vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) are two typical modes of vehicle communication in VANETs. Envisioned applications such as traffic accident prevention, battlefield control commands transmission and emergency coordination rescue arose a great deal of academic and industrial research on Vehicular Ad hoc Networks. In this research, developed a new security scheme called elliptic curve cryptography and ESSAP uses an algorithm to create the encrypted string. Using the encrypted string elliptic curve cryptography generated a docket, which will be transmitted from one node to another. The receiver node may desire to know that the docket has not been attacked in transit. In proposed research from our usage demonstrate that elliptic curve cryptography can ensure multicast source legitimacy and fundamentally upgrade the effectiveness of verification for multicast correspondence in VANETs, and our execution demonstrates that elliptic curve cryptography plan can be effortlessly conveyed in genuine vehicular ad-hoc network condition.
