通过分析基于重路由的匿名通信系统模型,提出一种适合节点在环境恶劣、性能不稳定条件下工作的N路冗余重路由算法,对使用该算法的匿名通信系统的可靠性、负载特性和匿名性进行理论推导和分析,结果证明,该算法能满足用户提出的可靠性边界条件,较大地提高重路由路径的可靠性并保证系统的匿名性,但会增加节点负载,减小系统容量。

Reroutiug mechanism is the main kind of the method to achieve anonymous communication system. Based on the model of rerouting-based anonymous communication system, this paper gives a new rerouting arithmetic that can build the rerouting path with N-path redundancy and work well in hard conditions. It calculates rerouting path dependability of the system and payload performance of the nodes, and analyzes its anonymity. The result shows that the N-path redundancy rerouting arithmetic satisfies the user＇s requirements for dependability, and it increases the dependability of the rerouting path and ensures the sender＇s anonymity. But it increases the node＇s payload and decreases capacity of the system.
