摘　　要：基于可信计算中可信性影响因素,详细地讨论了基于模糊集合理论的可信计算信任模型的评估方法。把模糊逻辑推理同信任传递结合起来,采用基于相似度的加权模糊推理方法得到委托实体的可信度,评价信任模型的可信性,为可信计算信任评估提供了一种新的思路。According to the influence factors of trust ,this paper discusses detailedly a trust level evaluation model of trusted computing models based on fuzzy logic.This model can gain the trust value between entities which have no direct recommendation by the fuzzy reasoning method,and the properties of trusted models are evaluated based on the trust level calculated.The proposed formal model provides a new valuable way for studying trust evaluation of trusted computing models.
