Abstract

Vehicular ad hoc Networks (VANETs) are an emerging technology with robust applications in Intelligent Transport System. It consists of smart vehicles and roadside infrastructure which communicate through open access wireless networks. The rapid growth in vehicles results in VANETs becoming large-scale, dynamic, heterogeneous and it is possible for the attacker to harm vehicular communication which leads to life-endangering situations. VANETs must ensure secured vehicular communication using strong privacy-preserving and authentication mechanisms. In addition, efficiency is also a major concern in VANETs. Numerous studies have been discussed in literature for VANETs privacy and security. Nevertheless, no one covered the privacy and security issues as a holistic view. In this paper, we have given a detailed background overview of VANETs. Details of different possible attacks in VANET are also given in this paper. We have classified privacy and authentication schemes into four major groups with their security mechanisms, security requirements, strength, limitations, attacks countermeasures and performance measures. Finally, we have discussed some open issues in the field of VANETs security.

Summary

INTRODUCTION

In the modern era each and every thing is going toward automation to facilitate and save the human being from unexpected incidents. Vehicular Ad Hoc Networks (VANETs) are one of the prominent factors of smart and autonomous Intelligent Transport System[1] in which vehicles can communicate with each other and roadside infrastructure [4]. All of the involved entities in VANETs communicate with each other over the insecure network Security is another main issue regarding VANETs. Since different nodes (i.e OBUs, RSUs) are exchanging sensitive information with each other and there is a chance of leakage of such sensitive information. If the driver of the vehicle is warned at least one-half second prior to vehicle collision about 60% of the road accident can be avoided [28] Another main issue is the traffic jams which cause fuel wastage. In this work we focus on different lightweight security techniques that help the driver from future harm
