摘　　要：随着匿名网络的大规模应用,针对匿名网络的追踪手段层出不穷。传统的多代理匿名系统构建通信链路的方法简单,模式单一且存在脆弱性,通过流量分析技术追踪者可以轻易匹配关联通信双方的通信关系进而攻击。提出一种动态路由算法,节点带宽作为性能指标,以追踪者占据通信链路节点的概率作为安全指标,通过改变算法的参数动态调节系统性能与安全性之间的平衡。通过实验有效证明了该算法对匿名网络安全性的提升。With the large-scale application of anonymous networks,the tracking methods for anonymous networks emerge in succession.The traditional methods of constructing the communication link are simple and vulnerable,and thus the attackers can use the traffic analysis technology to match the communication between the two hosts and launch attack.We propose a dynamic routing algorithm,which uses the bandwidth as the performance index,and the probability to track occupied communication link node as the safety index.It dynamically adjusts the balance between performance and security of the system by changing the parameters of the algorithm.The algorithm is proved to improve the security of anonymous network.
