云服务可信性量化模型研究

Research on Quantitative Model of Cloud Service Credibility

针对目前云计算平台有可能被恶意利用及云服务提供商不被信任的问题,迫切地需要建立一个客观、有效的方法来评估云服务是否可信。已有的研究缺乏完善的云计算可信性测评框架和质量模型。基于典型的云服务应用,研究云平台可信性的指标体系,通过对可信性质量属性建模,建立云服务可信性量化评估模型,从而指导云服务可信性评估方法的建立。最后,给出了模型分析和应用模式,验证了所提出的模型的有效性。

In view of the problems that current cloud computing platform may be maliciously used and the cloud service providers may not be trusted, it is urgent to establish an objective and effective method to assess whether the cloud service is credible. However, there is no perfect credibility evaluation framework and evaluation model of cloud computing in the existing researches. Based on the typical cloud service application, the index system of cloud platform credibility is studied, and the quantitative evaluation model of cloud service credibility is established by modeling the quality attributes of credibility, so as to guide the establishment of cloud service credibility evaluation method. Finally, analysis and application modes are given to verify the effectiveness of the proposed model.
