信任度评估是基于行为的信任管理模型关注的核心内容。为使信任度评估所依据的证据源完备,运用信任管理思想方法,提出一种基于多维证据的信任度评估模型,该模型将主体网络操作行为层面的信息引入传统仅考虑交易反馈信息的信任度评估模型,基于交易反馈和网络操作行为两个层面的多维证据源进行信任计算,扩展了证据源,突破了只依据单一种类证据源进行信任评估而引起的缺陷;另外,应用改进的D-S证据理论来合成多维证据,较好地解决了证据不确定性的问题。
The evaluation of trust is the core of the behavioral trust management model. In order to complete the evidence base of trust evaluation, this paper proposes a confidence evaluation model based on multidimensional evidence by using the method of trust management. This model introduces the behavior information of the main network into the traditional trust which only considers the feedback information Evaluation model based on transaction feedback and network operation behavior of two-dimensional multi-dimensional evidence source trust calculation, expanding the source of evidence, breaking through only a single type of evidence source trust evaluation of the defects caused; In addition, the application of improved DS evidence theory To synthesize multidimensional evidence and solve the problem of evidence uncertainty.
