Evaluation of Mutual Anonymity in P2P Networks

摘要

Anonymity is an important issue in nowadays networks. In this paper we propose mutually anonymous protocol for decentralized Peer-to-Peer (P2P) systems. The protocol is a combination between the Secret-Sharing-Based Mutual Anonymity Protocol (SSMP) and the information slicing technique. The proposed protocol realizes the initiator's and responder's anonymity by using the SSMP in which the complete reply-confirm interaction between responders and initiators is realized using the information slicing algorithm. Moreover, we evaluate the initiator's anonymity in a P2P network from probability point of view. The results show that the proposed mutual anonymity protocol provides higher anonymity than the conventional methods.
