Attack-resistant techniques in P2P reputation systems

The success of a reputation system depends on accurately calculated reputations that predict the quality of future interactions. In the peer-to-peer (P2P) networks, the scores are distributed by each peer locally or managed by the server/super-nodes. Similar to all other security mechanisms, reputation systems in P2P networks can be under attacks. Some attacks may attempt to exploit the system to its own benefits by deceiving or misleading. This paper focuses on trust model based on both direct and indirect feedbacks. The attacks-defense mechanisms by the trust model with credibility and community context factors are also explored.
