Vehicle ad-hoc networks has significantly used in automobiles for an effective communication with one another. The decentralized nature of this network provides an extensive range of applications which makes passenger safety and comfort. Providing security in a physical environment is considered to be the main issue to cope with. Vehicle-to-vehicle communication is the wireless transmission of data between the vehicles. It is more efficient and it enables 360 degree awareness of the surrounding threats. To overcome this issue a popular approach is recommended in VANET, is that cars are connected together via V2V,which are able to share data with one another, so that there is, less possibility of collision and other mischievous behaviour i.e. drunken drive. Although there are many proposed solutions for improving securities in VANET but security still remains a delicate research subject. The main objectives of this paper is to improve the security issues in VANET.

INTRODUCTION Intelligent Transport System (ITS) is a technology applied to transport and infrastructure to transfer information between systems for improved safety. The advancement in vehicular ad hoc networks (VANETs) have elevated the intelligent transportation systems (ITSs) to higher levels and also made vehicle telematics more attractive to the public. In VANETs, each vehicle is equipped with an on-board unit (OBU) communication device, which allows them to communicate not only with each other, i.e., vehicle-to-vehicle (V2V) communications, but with roadside units (RSUs), e.g., vehicle-to roadside (V2R) communication. Due to this hybrid architecture of VANETs, a variety of promising applications, ranging from safety (e.g., Emergency and Accident) to non-safety (e.g., infotainment), can be enabled to improve the road safety and better driving experiences. With an immense improvement in technological innovations, we find Vehicular Communication as a solution to many problems of our modern day communication system in roads. VC involves the use of short range radios in each vehicle, which would allow various vehicles to communicate with each other which is also known as V2V communication and with road side infrastructure V2I communication. These vehicles would then form an instantiation of ad hoc networks in vehicles, popularly known as Vehicular Ad Hoc Networks. A Vehicular Ad-Hoc Network, or VANET is a technology that uses moving vehicles as nodes in a network to create a mobile network. VANET turns every participating vehicle into a wireless router or node, allowing vehicles approximately 100 to 300 meters of each other to connect and, in turn, create a network with a wide range. As vehicles fall out of the signal range and drop out of the network, other vehicles can join in, connecting vehicles to one another so that a mobile Internet is created. VANET is mainly designed to provide safety related information, traffic management, and infotainment services. Safety and traffic management require real time information and this conveyed information can affect life or death decisions. Simple and effective security mechanism is the major problem of deploying VANET in public. Without security, a Vehicular Ad Hoc Network (VANET) system is wide open to a number of attacks such as propagation of false warning messages as well as suppression of actual warning messages, thereby causing accidents.
