【 摘 要 】

A vehicular ad hoc network(VANET) system used in modern transportation system that improves the road safety and other efficiency parameters. In this technology it uses cars as node in a network to develop a mobile network. In vanet, the distance between cars around 100 to 300 meters and only those ones are allowed to connect together. The broadcast of messages by vehicles are in an open-access environment. It makes several critical security issues. A mishandling of this information may cause several critical issues like traffic accident and other traffic problems. So authentication of vehicles is necessary to improve the safety in vanet. During authentication a vehicles confidentiality-related data, such as identity of user and information about locations must be kept private. There are different types of authentication schemes are available and preserving the privacy related data of vehicles are different in different authentication schemes. This survey aims to find the better schemes for privacy preserved authentication methods in the VANET system.
