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。
信任度評估是基于行為的信任管理模型關註的覈心內容。為使信任度評估所依據的證據源完備,運用信任管理思想方法,提齣一種基于多維證據的信任度評估模型,該模型將主體網絡操作行為層麵的信息引入傳統僅攷慮交易反饋信息的信任度評估模型,基于交易反饋和網絡操作行為兩箇層麵的多維證據源進行信任計算,擴展瞭證據源,突破瞭隻依據單一種類證據源進行信任評估而引起的缺陷;另外,應用改進的D-S證據理論來閤成多維證據,較好地解決瞭證據不確定性的問題。

The trust assessment is the core content of the trust management model based on the behavior.In order to complete the evidence sources of the trust assessment,a trust assessment model based on multi-dimensional evidence was proposed by using the trust management thinking.And this model introduces information on operating behaviors level of the main network into the traditional trust assessment model which only considerates feedback information of transaction,and computes trust based on multi-dimensional evidence sources on feedback information of transaction and network operating behaviors level,and extends the evidence source,and overcomes the defect when trust is assessed on-ly according to a single type of evidence source.In addition,the application of the improved DS evidence to synthesize multi-dimensional evidences can solve the problem of uncertainty of evidences.
