Abstract. With the growth and advancement in Intelligent Transport Systems comes the comfort and ease of driving at a rapid pace. People are also able to get both information and entertainment services when they are travelling. However, as Intelligent Transportation System (ITS) is becoming popular, the number of attacks on Vehicular Ad-Hoc Network (VANET) has also increased. One of the most important security threats is authenticity since most of the on road decisions are taken on the basis of the messages received. This paper proposes a simple decision making algorithm that helps in determining the authenticity of the occur‐ rence of an incident and thus helping the vehicle under consideration to take decision regarding its future mobility pattern. Keywords: VANET · Authentication

Background
The last two decades has seen a tremendous increase in the number of vehicles. In addition to this, passengers on board are demanding various web based services. It has therefore become necessary to bring tremendous changes in the Intelligent Transport System (ITS) that is in existence. Some of the prime services provided by ITS are ensuring on-road safety and infotainment services using internet. This has led to the introduction of a new domain known as Vehicular Ad-Hoc Network (VANET) which is one of the popular components of ITS and a famous application of Mobile Ad hoc Network (MANET). One of the distinguishing characteristics of VANET is that the pattern of the network is determined by the position of the nodes. The units that partic‐ ipate in a VANET change their positions very frequently and there is also no restriction in their energy consumption. One of the main objective of VANET is to support exchange of safety information among the mobile nodes that participate in the VANET. If the VANET is attacked, it can result in both financial loss and loss of lives. Thus, it is very necessary to ensure the security of VANET. This paper discusses the various security challenges in VANET, the major attacks, brief review of some of the existing solutions and a proposal of a new security model and algorithm.

VANET
Vehicular Ad-Hoc Networks (VANET) is an application of MANET in which vehicles communicate with each other with the help of internet by forming an ad-hoc wireless network. Possibly, communication in VANET can occur in two modes, namely, Vehicle to Vehicle (V2V) and Vehicle to Road Side Unit (V2R) communication. Vehicles in a VANET can also indulge in Hybrid communication in which both Vehicle to Vehicle and Vehicle to Infrastructure communication is combined. 2.1 Components of VANET Vehicles - Vehicles serve as nodes in a v
