Abstract: Rerouting 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.

Key words: anonymous communication, rerouting, dependability
