Abstract

The peer-to-peer network based on distributed hash table could locate the nodes effectively, but it cannot solve the node-failure problem. By introducing the concept of trust into anonymous communication system, this paper proposes a secure query method, in which, the nodes’ trust and the mutual distance between the nodes can be used to select high reliable nodes to construct anonymous communication path. The novel method could alleviate the node-failure problem, and further to improve the message forwarding efficiency.
