Abstract—With internet boom, since more and more people share resource with each other through internet platform, peer-to-peer has become very popular in recent years. In theP2P environment, all nodes share resource with identities as anonymous users, and don’t need to account file content they upload, as a result, some node does some malicious work through this leak, and reduce the service quality of internet, which makes security issue on internet very important. In this paper, we design “The Trust Model of Multiple Factors” to calculates the trust value of nodes with multiple factors, and node will choose its own provider through this. Many malicious behaviors may be avoided by this model, and we expected this model to increase download success rate and moreover, it may decrease the number of malicious behaviors on internet.

Index Terms—Trust model, trust evaluation,peer-to-peer, network security.
