When Game Theory Meets VANET's Security and Privacy

Abstract

Vehicular ad hoc networks (VANET) are one of many fields that faces numerous challenges in terms of security and privacy. Risk and security assessments approaches in this kind of networks may not be able to operate correctly in all the vehicular systems, because theses analyzes aspects are based generally on theoretical ideas, which may not reflect any realistic conditions. The important motivations of VANTET applications deployment is the reduction of the accident traffic and the numbers of human deaths and injuries, hence this applications have a stiff security requirements. In order to cover all possible security requirements many research approaches were presented, such as approaches based on attack tree process, where we find also the attack-defense tree approach. This paper focus on the existed trade-off between the attacker and the defender in a vehicular system, also we tries to find an equilibrium point that reflect this relationship through the application of a mathematical analysis, which is the game theory analysis. Game theory approach where firstly deployed in the ad hoc networks by many researches, which is not the case for the vehicular systems where we find a few number of researches dedicated to the use of the game theoretic approach for the security or the privacy preserving in this kind of networks. For a better understanding, we start the paper by presenting some works that highlight the application of game theory in order to address the different forms of security and privacy issues in ad the ad hoc networks and more precisely the vehicular ad hoc networks. Where we show how different interactions between attackers and defender in the vehicular networks can be modeled as a game.
