A Survey on the Major Security Issues in VANET

Vehicular Ad hoc network (VANET) is an emerging infrastructure less network. VANET is developed by applying the techniques of Mobile ad hoc networks (MANET) in the field of vehicles. It is a communication network which provides safety measures and traffic analysis to users while driving. VANET is also known as Intelligent Transportation networks. It plays a major role in reducing accidents and improving traffic on the roads. Security is always an issue in the field of networking. Here it is also playing a major role because its sharing safety information to the users and exploitation of this information can create a huge loss. In this Survey paper, we discussed the existing security threats and attacks i. e. availability and confidentiality with their challenges and future scope.
