Abstract

Peer-to-Peer (P2P) computing has become a popular application model because of its easy resource sharing pattern and powerful query search scheme. However, decentralized P2P architecture is scarcely seen to deploy the anonymity on its peers. In this paper, we propose a mutual anonymity protocol, called Secret-sharing-based Mutual Anonymity Protocol (SSMP),for decentralized P2P systems. SSMP employs Shamirs' secret sharing scheme to allow peers to issue queries and responders to deliver requested files anonymously. Compared with pre-vious designs, SSMP achieves mutual anonymity in P2P systems with a high degree of anonymity and a low cryptography processing overhead. We evaluate SSMP by comprehensive simulations.
