摘　　要：提出了一种静默池机制方法(SPA,silent-pool approach),当传感器节点感知到附近移动攻击者的存在,通过控制节点的转发状态从而阻止和减少攻击者收到有效数据分组。在此基础上,进一步提出了对当前路由路径没有任何影响的安全机制——池外虚假信息注入(DPIOP,dummy packet injection out pool)法,诱使攻击者远离传输路径。实验结果验证了SPA和DPIOP的隐私性能,与现有方法相比可减少能耗约为63%,降低时延约为35%。Sensors’ ability was utilized to perceive the mobile attacker nearby, and SPA （silent-pool approach） was pro-posed, which was able to hinder or reduce the packets hunted by the attacker by controlling the forwarding state of the nodes. In addition, a novel DPIOP （dummy packet injection out pool） method was proposed to entice the adversary far away from the transmission path without changing the original routing path. Through simulation studies and experiments, the outstanding performance of SPA and DPIOP in privacy preservation were demonstrated, with saving energy by about 63%, and reducing delay by about 35%.
