Research of subject trust comprehensive evaluation model based on fuzzy theory
基于模糊理论的主观信任综合评价模型研究*

Trust is an important guarantee for secure communications in the open networks. This paper proposed subject trust comprehensive evaluation model based on the fuzzy theory according to the subject trust evaluation with uncertainty. Then studied the application of fuzzy theory in the proposed evaluation model, and discussed the definition mechanisms of trust problem and the evaluation mechanisms of trust. At last, the actual example indicates that the model is reasonable, effective and practical. The simulation experiments show that the method can make the network performance improved.
