P2P网络中一种可信访问控制模型

信任模型强调成员以及数据的可信性，通过对网络中的不端行为进行通告和限制，为用户能够更加合理地使用网络提供保证。提出了一个基于相似度加权推荐的全局信任模型（GSTrust）。在模型中，信任值的请求者使用推荐者和自己之间的节点评分行为相似度加权推荐意见，以节点评价行为的相似度加权其推荐度计算全局信任值，并提出了基于群组的激励机制作为信任模型的有效补充，仿真实验证明了模型的有效性。

A credible access control model in P2P networks

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.
