Review of Prevention Schemes for Modification Attack in Vehicular Ad hoc Networks

What is it about?

Vehicular Ad-hoc Network (VANET) technology is the basis of Intelligent Transportation System (ITS) connectivity that enables the delivery of useful information to and fro between vehicles in vehicle-to-vehicle communication mode; or between vehicle and infrastructure in vehicle-to-infrastructure mode for safety and comfort. However, due to the openness of the wireless medium used by VANET, the technology is vulnerable to security threats in both communication modes. In this study, the essential background of VANET from architectural point of view and communication types are discussed. Then, the overview of modification attack in VANET is presented. In addition, this paper thoroughly reviews the existing prevention schemes for modification attack in VANET. This review paper reveals that there is still a need for a better and more efficient preventive scheme to address the modification attack in VANET.

Why is it important?

he open nature of the wireless communication medium used by VANETs exposes the information exchanged to various types of attacks, such as modification attack. It is common for attackers to alter or modify the intercepted message in V2V and V2I communication. The attackers could deliberately send false information to VANETs to create confusion for vehicles which could lead to severe safety consequences. The presence of modification attack in VANET could result in high computational and communicational costs due to the frequent updates of bogus traffic-related message. The receiver must always check and verify all the messages received from other vehicle to avoid falling victim to modification attack.
