A credible access control model in P2P networks
P2P网络中一种可信访问控制模型

Trust model emphasizes credibility of member and data. By proclaiming and restricting the misconduct of networks, it can provide guarantee for users to use the Internet more reasonably. A global trust model (GSTrust) was proposed based on similarity weighting recommendation. In this model, the trust value's requester weighted recommendation by using similarity behavior of the presenter and himself, and calculated the global trust value by using the similarity score to weight its recommendation. An incentive mechanism also was proposed based on group as the effective complement for trust model. Simulation experiment shows the good performance of GSTrust model.
