摘　　要：在无线传感器网络源位置隐私保护问题中,针对具有局部流量分析行为的逐跳反向攻击者,提出了基于随机角度和概率转发的源位置隐私保护路由协议RAPFPR。该协议主要分为两个阶段:真实源节点根据随机角度和距离的有向路由阶段,幻影节点到基站的概率转发路由阶段。协议产生的幻影节点能够很好地均匀分布在真实源节点周围,且采取概率转发路由大大减少了重合路径的产生,增加了逐跳反向攻击的难度。仿真结果表明,与现有的隐私保护方案相比,该路由协议能够在不显著增加通信开销的前提下,有效延长网络的平均安全时间,具有很好的隐私保护性能。In wireless sensor networks （WSN） source location privacy protection issues, aiming at hop by hop back- tracking attacker with the ability of local traffic analysis, a source location privacy routing protocol RAPFPR based on random angle and probability forwarding is proposed. The protocol is mainly divided into two phases： the true source node according to the random angle and distance directed routing phase and the phantom node to the base station based on probability forwarding routing phase. The protocol of the phantom nodes can evenly distributed around the true source node, and probability forwarding routing greatly reduces the probability of overlapping path, increased the diffi- culty of hop by hop reverse attacker. Compared with the existing privacy protection scheme, simulation results show that under the premise of without significantly increasing the communication overhead, this protocol can effectively pro- long the average network safety time and has a very good privacy protection performance.
