为了在设计之初对IaaS平台安全性评估提供科学依据,提出了专门适用于IaaS平台的耦合度计算方法.对IaaS耦合行为进行了抽象描述,并解释了IaaS平台耦合行为的特点,然后系统地归纳了IaaS平台耦合度的结构,并针对该结构基于改进的结构熵方法实现了IaaS平台耦合度的计算.最后以已有的IaaS平台为例,利用所提出的方法进行了平台耦合行为的抽象分析并计算了其耦合度,验证了该方法的可行性.计算结果表明:该方法的结果符合其实际设计情况,可以较好地对平台耦合程度进行量化,能够在设计之初为平台架构的安全性评估提供参考.
In order to provide a scientific basis for the safety evaluation of IaaS platform at the beginning of the design, a coupling calculation method specifically for IaaS platform is proposed.The abstract description of IaaS coupling behavior is given, and the characteristics of IaaS platform coupling behavior are explained, The structure of coupling degree of IaaS platform is summarized, and the coupling degree of IaaS platform is calculated based on the improved structure entropy method.Finally, using the existing IaaS platform as an example, the proposed method is used to abstract the platform coupling behavior The coupling degree is analyzed and calculated, and the feasibility of the method is verified. The calculation results show that the method is in accordance with the actual design situation and can quantify the degree of platform coupling. Provide a reference for safety assessment.
