摘要
研究涉及一种基于分区操作系统的文件系统设计方法,解决分区操作系统下文件的安全访问问题.分区操作系统资源、空间彼此隔离,文件系统用于管理分区数据,不能违背数据资源的隔离需求.为此,通过将文件系统部署在分区操作系统的分区;分区内和分区外采用两层分区安全访问控制;采用快照管理实现文件系统自身对并行文件访问需求,实现文件系统设计.通过测试表明,该方法能够在满足分区操作系统设计约束下,实现文件的安全访问.
Abstract
This paper involves a file system design method based on partitioned operating system to solve the problem of secure access to files under partitioned operating system.The partition operating system re-sources and space are isolated from each other,and the file system is used to manage partition data,which cannot violate the isolation requirements of data resources.To the end,the file system is deployed in the partition of the partition operating system,two-layer partition security access control is adopted inside and outside the partition,and snapshot management is used to realize the file system's own parallel file access requirements,so as to realize the file system design.The test results show that the proposed method can a-chieve secure access to files under the design constraints of the partitioned operating system.
