摘　　要：入侵检测是传感器网络安全的重要研究内容,论文基于博弈论中的非合作模型提出了一种新型传感器网络入侵检测方案。该方案用一种只有两个参与者(攻击者和传感器网络)的非零非合作博弈模型来描述传感器网络中入侵检测问题,并证明了这个博弈模型可以达到纳什均衡,据此可以制定一个防御策略有效地提高入侵被检测到的概率。模拟试验证明这一模型是有效可行的。In wireless sensor network, the network security is a serious problem. In network security, the attack tries to handle some network nodes, but the nodes try to defense. In this paper, we define a non cooperative game between the attacker and defender and propose a new security model by the game. We formulate the attack-defense game as a twoplayer, nonzero-sum, non cooperative game, and show that this game achieves Nash Equilibrium, thus leading to a defense strategy for the network and significantly increases the chance of detecting intrusions. We have proved the model proposed in this paper to be efficiency.
