Vehicular ad hoc networks (VANET) are a class of ad hoc networks in which vehicle communicate with each other to show the traffic scenario and any mishappening on the road. It also ensures the safety on the road. Trust and security remain a major concern in VANET as simple mistake can cause serious problems. A crucial point in VANET is how to trust the information transmitted when the neighbouring vehicles are rapidly changing and moving in and out of range. This obstructs establishing reliable end-to-end communication paths and having efficient data transfer. In a VANET, vehicles will rely on the integrity of received data for deciding when to present alerts to drivers. The communication between vehicle to vehicle and vehicle to roadside unit is done through wireless communication. That is why security is an important concern area for vehicular network application. Also in VANET efficient routing protocols are needed as vehicles are changes their positions very rapidly. In this research paper we are going to analyse and categories various security issues in VANET based on various security requirements. Also we have given the various security challenges faced in VANET that are given in various research papers.
