Building a hybrid trust model for P2P systems
构造P2P环境下混合式信任模型

In order to resolve the problems of P2P network, such as security, bad management and complex computation of trust worthiness in current trust model, a hybrid trust model in P2P system was proposed. This model adopted the hybrid P2P network structure, and time section mechanism for computation trust level, which could efficiently prevent malicious actions amongst peers, such as "exaggeration" and "slander", etc. In addition, the building method and the way of evaluation feedback of the model were proposed. The simulation proves that this model has little computation workload, and can isolate and identify the malicious peers efficiently, with high performance of security.
