Abstract: A wireless network is subject to various security attacks because of openness and topological dynamic variation. The existed anonymous communication models are unable to completely adapt the wireless network which has open link, dynamic changes of topological structure and limited resources. The paper proposes a multistage coding-confusion anonymous forwarding mechanism. The mechanism combines with multipath transmission and changes the correspondence and external form of the in and out packets to improve the ability of against flow-analysis attacks by internal packets random encoding at each node. Meanwhile, the mechanism improves the anonymity of system.

摘要: 无线网络的开放性、拓扑动态变化性决定它容易受到多种攻击的威胁,现有的匿名通信模型都无法完全适应链路开放、拓扑动态变化、资源有限的无线网络。提出了一种多级编码混淆的匿名转发机制,该机制通过在各个节点进行内部数据包随机编码,使各个节点出入的数据包对应关系及信息形式发生变化,结合多路径传输方式,提高了匿名通信抗流量分析攻击的能力,同时改善了系统的匿名性。
