针对流量分析中三类常见攻击方式,即速率监控攻击、时间相关性攻击与ID分析攻击,对多跳LEACH无线传感器网络构成的威胁,提出了基于多跳LEACH路由协议的分布式位置隐私算法( Distributed Location Privacy Algorithm,DL-PA)与匿名通信算法( Pseudonyms Communication Algorithm,PCA)。 DLPA将“路径多样化冶与“伪装包注入冶相融合,PCA通过动态产生的假名片隐藏所有参与通信节点的真实ID。仿真结果表明,该算法实现了数据包传输路径的多样化,隐藏了节点ID与网络流量模式,能够抵御流量分析攻击,保护基站位置隐私。

In view of the threat of three common traffic analysis attacks,rate monitoring attacks,time correlation attacks and ID analysis attacks,to the multi-hop LEACH WSN,propose a Distributed Location Privacy Algorithm ( DLPA) and an Pseudo-nyms Communication Algorithm ( PCA) ,which are based on multi-hop LEACH routing protocol. DLPA manages to combine routing path diversity with fake packet injection while PCA is to hide identities of all nodes that participate in packets transmis-sion by generating pseudonyms dynamically. Simulation results show that this algorithm realizes the diversity of data packet transmission path,concealing the true network traffic pattern,which can resist the traffic analysis attacks,protect the location privacy of base station.
