摘　　要：当前已有不少基于重路由的匿名通信系统,但现有的匿名通信系统大部分在获得匿名的同时却牺牲了效率。为设计既安全又高效的匿名通信系统,提出基于重路由技术的匿名通信系统改进模型,对匿名系统的匿名度进行探究。模型根据敌手攻击能力的不同,提出两种改进方式:对于敌手攻击能力为1的情形,提出单一节点和多节点的信息熵偏差模型,该模型能够用于不同系统之间匿名性的比较,客观、合理地给出各个节点的权重;对于敌手攻击能力为0.95的情形,引入模糊熵的概念与非线性规划模型,运用模糊熵与概率熵相结合,充分利用模糊随机变量整合所有不确定性,理论分析表明,改进后的重路由算法均能有效保证匿名性能。基于给定的匿名系统信息发送概率,设计实例求解系统的匿名性并做比较分析,实验结果表明,改进后的匿名系统度量模型具有较好的可靠性与优越性。Currently,there are many anonymous communication systems based on rerouting,but most of the existing anonymous communication systems lose efficiency while gaining anonymity.An improved anonymous communication system model based on the rerouting technology is proposed and the anonymity of the system is explored to design a safe and effective anonymous communication system.The two improved modes of the model are proposed according to the different attack ability of the adversary.In allusion to the case that the attack ability of the adversary is 1,the information entropy deviation model of single node and multi⁃node is proposed,which can be used to compare the anonymous performance of different systems and give the weight of each node objectively and reasonably.In view of the case that the attack ability of the adversary is 0.95,the concept of fuzzy entropy and nonlinear programming model are introduced,and the combination of fuzzy entropy and probability entropy is used to integrate all uncertainties by fully utilizing the fuzzy random variable.The theoretical analyses show that the improved rerouting algorithm can guarantee the anonymous performance effectively.Based on the given information sending probability of anonymous system,an example is designed to solve the anonymous performance of the system,and its results are compared.The experimental results show that the improved metrics model of the anonymous system has better reliability and superiority.
