摘要： 云计算的安全性问题不仅是安全技术自身问题,也涉及到云系统的可靠性、保密性、信息匮乏等相关问题.为了增强异构、独立的云计算环境的安全性,提出一种云可信赖性模型CDMV(cloud dependability model by virtualization techniques),主要贡献体现在以下两个方面:提出了一种新的具有较好可扩展性、通用性的云系统可信赖性模型CDMV,并系统分析了CDMV模型的可信赖特性;给出了云系统可信赖性的定义及可信赖性的度量指标,并予以量化分析.

Abstract: Security issues in cloud computing are not all technological, rather, it is the issue of reliability, confidence, and lack of clear and enough information about cloud security. In order to improve the security of heterogeneous independent cloud environments, a novel cloud dependability model named CDMV (cloud dependability model by virtualization techniques) is proposed by using virtualization techniques. Our contributions can be summarized as follows: a general formal CDMV model with good scalability by using system-level virtualization techniques for cloud systems is proposed, and systematic analysis on how CDMV model can enhance the system dependability is presented; the proposed CDMV construction is equipped with the definition of dependability in cloud systems and a series of quantitative indicators to evaluate the dependability, which are missing in most existing schemes.
