A VANETs Attack-Defense Game

Abstract

The existing risk analysis solutions may not work well to evaluate the security threats in vehicular networks due to the lack of considering the attack and defense costs and gains, and thus cannot appropriately model the mutual interaction between the attacker and defender. In this study, we consider both of the rational attacker and defender who decide whether to launch an attack or adopt a countermeasure based on its adversary's strategy to maximize its own attack and defense benefits. We investigate the potential strategies of the defender and the attacker by modeling it as an attack-defense game. The equilibriums of the game are given and the rationality of the proposed game-theoretical model is illustrated by a detailed case study.
