Abstract
In order to improve the security of user data in the cloud computing environment,in addition to ensure that the tra-ditional static data security element can not meet the security requirements,in this paper,a data integrity protection model is pro-posed,which is based on a variety of security policies,including static data and dynamic data. For the establishment of user trust in security static data cloud storage platform,a dynamic update and publicly verified data integrity protection scheme is proposed, which provides remote data integrity verification for the users decentralized information flow control based on the theory,a decentral-ized information flow control model is proposed to protect data security,in order to achieve the fine-grained tracking of data ob-jects,and for different users of cloud computing data isolation and protection.关键词
