Analysis on anonymity of P2P anonymous communication system
Chenfei Xu, Hua Zhang, Qiaoyan Wen · 2015
Most of existing anonymous communication systems adopt "mixes" nodes to encrypt and relay the communication messages.Extensive works have been done on this field to find methods that can effectively resist the attacks.However, the adversaries can perform the attacks through the relationship between multiple nodes communication traffic to deanonymize the P2P anonymous systems.To address this problem, this paper presents a novel concept: "Cluster Node" in P2P system, which uses a method of "Cluster" statement and adopts a limited strategy of node selection to avoid using multiple nodes from the same cluster in the same circuit.We show the feasibility and accuracy of our approach by theoretical analysis and validate experiment.
