| 摘 要： | 针对现有的P2P系统信任模型在信任度的计算上过于复杂的问题,提出了一种基于模糊理论的动态可信度等级模型DTD(dynamic trust degree model)。该模型在通过对信任度的传递进行细粒度的分析,设计了一种计算对信任值传递的计算方法,并结合对直接信任度和推荐信任的多级别综合评价而获得最终的信任度。模型将P2P系统中信任的计算转换为了一种可计算的表达式,简化了信任的计算过程,使信任的计算变得更加灵活。

| Abstract: | In the traditional P2P trust system,a very complex issue is how to calculate the trust value.This paper introduced a trust degree based fuzzy theory model named DTD.This model not only designed a calculation of transfomed trust by the fine-grained analysis,but also got the final turst value with a multilevel comprehensive evaluation method for direct trust and recommended trust.The model transformed compute trust to a computable expression in P2P system,and simplified the process of trust calculation,made the calcution of the trust become fexible. |
