摘要针对当前云服务信任评估研究存在的问题，提出一种基于上下文溯源和语义规则的信任评估方案，保障云服务的可信性和安全性。引入数据溯源理念，在需求分析的基础上构建云服务信任评估框架，并就框架的各个功能模块进行了详细的论述和分析。运用PR O V 模型对云服务的上下文溯源信息进行了分析和描述，并设计了基于“提问-反馈”的语义评估规则，详细阐述了云服务信任度的计算过程。分析结果表明，该方案可以有效地搜集和描述云服务的溯源信息，并通过语义规则进行信任评估，具有较好的适用性，可以为提升云服务的信任评估水平提供借鉴。
Abstract： According to the research limitation of trust evaluation of cloud service, this paper proposes a trust evaluation method
of cloud service based on context provenance and semantic rules. The method can ensure the credibility and security of cloud ser-
vice. A novel trust evaluation framework of cloud service is constructed by means of data provenance based on demand analysis, and
the function modules are designed and discussed exhaustively. Then, the context provenance of cloud service is described and ana-
lyzed by PROV model, and the“questions-feedback”semantic rules are designed. At last, the algorithms of computing trust degree
are discussed in detail. The analysis results show that the trust evaluation method can effectively collect and describe the provenance
of cloud service. The method can also improve the trust evaluation quality of cloud service by semantic rules.
