摘　　要：现有的匿名系统如tor容易被审查和被流量分析,导致隐私泄露问题。而云匿名系统通过跨云实施电路构建与数据传输,可以一定程度上对抗审查和抵制流量分析。然而,由于云匿名系统起步较晚,研究者并未对其性能评估问题给予足够的研究和重视,暂未形成云匿名系统性能度量方法。针对上述问题,论文提出了一种基于多云框架的匿名系统实现方案,克服匿名系统容易发生节点相互勾结和被流量分析等问题。同时针对该云匿名系统设计了一套性能评估方法,该方法对拓扑结构模型、敌手威胁模型、代价开销模型进行分析,实现对云匿名系统性能多维评估。Existing anonymous systems such as tor are easy to be censored and analyzed by traffic,leading to privacy leakage.The cloud anonymity system can counter censorship and resist traffic analysis to a certain extent through cross-cloud circuit con⁃struction and data transmission.However,due to the late start of cloud anonymity systems,researchers have not given enough re⁃search and attention to their performance evaluation issues,and have not yet formed a cloud anonymous system performance mea⁃surement method.In response to the above problems,this paper proposes an implementation scheme of an anonymous system based on a multi-cloud framework to overcome the problems that the anonymous system is prone to collusion between nodes and traffic analysis.At the same time,a set of performance evaluation methods is designed for this cloud anonymous system.This method ana⁃lyzes the topology model,adversary threat model,and cost cost model to achieve multi-dimensional evaluation of cloud anonymous system performance.
