无线网络的特殊性决定了它会受到多种网络攻击的威胁,目前的广播、代理、洋葱路由和包混淆等匿名通信模型都无法完全适应链路开放、拓扑结构动态变化、资源有限的无线网络.本文在比较分析了抗流量分析的匿名技术基础上,根据网络编码具有混淆与伪装数据的功能,提出了一种新型编码混淆匿名通信模型.该模型通过链路层编码混淆、网络层数据包拆分与多径路由等方法相结合,使路由节点数据包出入的对应关系和信息表现形式发生变化,提高匿名通信的抗攻击能力;新模型可以实现通信的保密性与匿名性.
The particularity of the wireless network determines that it will be threatened by many kinds of network attacks. The current anonymous communication models such as broadcast, proxy, onion routing and packet obfuscation can not fully adapt to the openness of the links, the dynamic changes of the topological structure, the resource-limited wireless network Based on the comparative analysis of the anonymous technology of anti-flow analysis, a new coding confusion anonymous communication model is proposed based on the obfuscation and camouflage of network coding.It uses the confusion of link layer coding, Split and multipath routing and other methods combine to make the correspondence and information expression of routing nodes change and improve the anti-attack capability of anonymous communication. The new model can realize the confidentiality and anonymity of communication.
