PRIVACY PRESERVING AUTHENTICATION SCHEME FOR VANET

In today’s era wireless communication technologies reformed human’s lifestyles by providing the best convenience and beneficial personal communication applications with the help of internet services. Recently, in vehicle manufacturers and telecommunication companies gear up to equip each car with the facility that allows the vehicle to vehicle communication with each other as well as with the roadside unit, which is located near by the road, such as at every traffic signal or any important location , in order to betterment in driving experience, facilitate secure driving, and enhance people safety. In Authentication and Privacy preserving in vehicular ad hoc network (VANET) paper requires secure and efficient authentication and communication with help of privacy preservation of every vehicle and also it requires facility to handle traffic details management. In this project proposed a TWO-Factor Light weight Privacy preserving authentication scheme to enhance the security of Vehicles in Ad-Hock Network communication. It includes the certificate authority (CA) Authentication and the textual Driver password based two factor authentication (2FA) to achieve the goals. System only requires several extreme lightweight hashing processes and a Onetime Password for message signing and verification between vehicles. Compared with previous schemes, System significantly reduces computation cost by more times. We use pseudonymous certificate to communicate to each other hence proposed scheme provides strong privacy preservation and third party can never access identity of any vehicles even if RSUs compromised.
