Abstract
As the application of computer technology continues to
proliferate and diversify, vehicles are becoming increasingly intelligent and it is expected that in the near future they will be equipped with radio interfaces for short range communications. This will enable the formation of vehicular networks, commonly referred to as VANETs, an instance of mobile ad hoc networks with vehicles as mobile nodes. Vehicular networks are receiving a lot of attention due to the wide variety of services they can provide and are likely to be deployed commercially in coming years. Security is a fundamental issue because such networks will provide the necessary infrastructure for various applications that can help
improve the safety of road traffic. Effective security of vehicular ad hoc network is an ill-defined problem as most existing security mechanisms available for VANET do not combine efficiency, security and traceability. They tend to score well in one or two qualities, but not all three because of the potential contradictions between some of their attributes.
In this paper, we give an overview of VANETs and the
security challenges related to their deployment. We identify and analyse current security limitations, then an effort is made to show that efficiency, security and traceability are the key qualities to consider while implementing an effective security mechanism. Therefore the most suitable way to achieve this goal is by identifying the intersection point connecting their
attributes.
