摘要：

目前对于云计算架构安全性的研究大多集中在架构设计和专项技术的改进上,缺乏对架构所处环境和相关因素的整体性思考与定量分析。针对上述问题,抽象化云计算架构安全性的因素和方法,从概率的角度对影响云计算架构安全的共同因素进行分析和一般性的理论证明,并给出一种关联长度的分块方法。安全性分析结果表明,云架构的安全性与数据的分级分类有关,通过提高数据安全等级细化程度或采用切分数据增强恢复数据的难度可以提高云架构的安全性。

Abstract:

The researches on the security of cloud computing architecture are mainly focused on the architecture design and some technology improvement which are lack of overall thinking and guantitative analysis on the environment and related factors of the architecture.This paper abstracts the regulars and factors of cloud computing architectures,and finds those who affect their security through probability prove.A method about how to cut data into blocks according to its length is given.Security analysis result shows that the security of cloud architecture is related to data classification,increasing data security level and data block cutting which enhancing the difficulty of data recovery can improve the security of cloud architecture.

Key words: cloud computing, cloud architecture, risk probability, security, data classification
