An immense amount of information is processed on the Internet due to its spread, increasing the severity of such problems as the disclosure of personal information; privacy protection is required. Research to protect anonymity has become crucial. Anonymous communication systems must consider a sudden breakaway of nodes. However existing systems isn't considering this enough. This paper proposes separating a node management layer from an anonymous communication layer. A novel anonymous communication system is realized by a node management layer that uses Chord, which is a distributed hash table, and the anonymous communication layer uses multiplex encryptions.
