摘要
云计算作为一种新型的服务模式,近年来受到各个企业的青睐.虽有云有三种部署模式,企业可以自己选择部署方式,但是云中数据存储和传输安全还是企业最为担心的.因此,运用了一种基于属性的控制策略方法(Attribute Based Access Control,ABAC)来保证只有授权用户才有权限来操作云中的数据.另外运用粗糙集属性约简的方法来减除冗余属性保留权威属性减少策略冲突问题的出现,加快访问时间.
As a new mode of service, cloud computing receives the favour of various enterprises in recent years. Though there are three kinds of deployment models to be chosen, enterprises also worry about the storage and transmission security of data. A method of Attribute Based Access Control（ABAC） was used to ensure that only authorized users had access to the data in the cloud. In addition, the method of rough set attribute reduction method was used to reduce the redundant attributes, retain authority conflicts and speed up the access time.
