摘　　要：针对主动攻击所发布车辆轨迹隐私的场景,利用信息熵量化攻击者和防御者的能力,采用博弈论对车辆轨迹隐私攻击和防御进行建模,并给出攻击和防御策略,分析了攻防双方之间的博弈过程。通过对真实轨迹数据分析,得出完全信息博弈下的纳什均衡点和相应攻击策略下的最优防御策略。The vulnerability of published vehicle traces is a focus issue for vehicle ad hoc network. Aiming at the privacy of published traces with a game-theoretic model under the scene of the active attacks and defense actions were modeled, and the attack and defense games were analyzed. Also ability of an adversary and the goal that a defender wants to achieve by the information entropy were quantified. By the analysis of true traces, the Nash equilibrium point under the game of complete information and an optimal defense strategy providing the user with the best privacy level for each attack strategy were presented.
