基于信息流控制模型的云计算数据隐私保护算法研究

Research on Cloud Computing Data Privacy Protection Algorithm Based on Information Flow Control Model

提出了一种信息流控制模型IFCM,将该模型集成到云服务管理器中可以实现云计算系统的隐私保护.IFCM提供了一个统一的解决方案,用于保护各种混合云(即私有云和公有云混合)架构.首先,阐述了IFCM模型的设计过程,并定义了信息流的语义.然后,将该模型集成到云服务管理系统中,最后,通过示例来说明该模型的工作流程,并验证模型的有效性.

In this paper,an information flow control model IFCM is proposed,which can be integrated into cloud service manager to protect the privacy of cloud computing system.IFCM provides a unified solution for protecting various hybrid cloud(i.e.hybrid private cloud and public cloud)architectures.Firstly,the design process of IFCM model is described,and the semantics of information flow is defined.Then,the model is integrated into the cloud service management system.Finally,an example is given to illustrate the workflow of the model and verify the validity of the model.
