摘要
在开放式网络环境中,信任是安全通信的重要保证。针对主观信任评价带有不确定性,建立了基于模糊理论的主观信任综合评价模型。研究了模糊理论在主观信任评价中的应用,给出了信任问题的定义机制和综合评价机制。最后通过实际数值例子证明了该方法具有有效性、合理性及工程可行性。通过仿真实验比较,证明了该方法能够使网络性能得到改善。
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.
