Vehicular Ad-hoc Networks (VANET) is an emerging technology for enhancing the safety measures of vehicles. To ensure safety and to keep track of accident prone zones, there is a need for communication between vehicles. The advantages of VANETs are that they upgrade traffic safety and vehicle security while shielding drivers' protection from assaults executed by enemies. Security is a standout amongst the most basic issues identified with VANETs since the data transmitted is dispersed in an open get to environment. VANETs confront many difficulties. This paper shows a study of the security issues and the difficulties they create. The different classes of uses in VANETs are presented, and additionally some security prerequisites, dangers and certain structures are proposed to take care of the security issue. Here, various authentication and secure key management mechanisms in VANET are reviewed and their advantages are listed. The performance metrics used in different technique for analysis are also studied.
