An Anonymity Scheme Based on Pseudonym in P2P Networks

One of the fundamental challenges in P2P (Peer to Peer) networks is to protect peers’ identity privacy. Adopting anonymity scheme is a good choice in most of networks such as the Internet, computer and communication networks. In this paper, we proposed an anonymity scheme based on pseudonym in which peers are motivated not to share their identity. Compared with precious anonymous scheme such as RuP (Reputation using Pseudonyms), our scheme can reduce the overhead and minimize the trusted center's involvement.
