| 摘 要： | 分析了现有云计算系统中机密性的几种保护机制,并提出了一种基于数据流分析的机密性风险评估模型。通过LKM部署的监控器截获系统调用获得系统的数据流,交由评估器与服务提供的数据流模式集进行比较分析,来对服务机密性进行综合评估。实验表明该方法能够有效识别云计算环境中破坏服务和数据机密性的行为。

| Abstract: | This paper analyzes several protection mechanism of confidentiality in existing computing clouds system,and proposes a risk assessment model of confidentiality based on data flow analysis.The Monitor deployed through the LKM(linux kernel module) intercept system calls to get data flow of the system,for comparing analysis of the data provided by the sensor and service flow pattern set,to evaluate the service confidentiality.The experimental results show that the method can effectively identify the destruction behavior of services and data confidentiality in cloud computing environment. |
