Embodiment Construction

[0049] The provision of storage cloud services mainly depends on the distributed file system of the basic management layer in the storage cloud architecture. The most popular and widely used distributed file system in the current society is HDFS (Hadoop Distributed File System, Hadoop Distributed File System), a sub-project of the Hadoop open source project based on Apache. The basic prototype of this patent was also developed using HDFS. In the specific development and implementation process, the idea of ​​AOP (Aspect-Oriented Programming) is adopted, so that the original code of HDFS is not modified, and the security policy of data migration is fully integrated in each aspect (Aspect), so as to achieve the greatest extent Reduce the coupling between the security migration strategy and the original system.

[0050] First, let’s introduce the platform for prototype development—HDFS, which is a master-slave structure system. An HDFS cluster includes a central node (NameNode no...

Abstract

The invention discloses a method suitable for secure migration of data in a storage cloud, belonging to the field of security of storage cloud environments. The method comprises the following steps of: (1) dividing storage cloud users into a plurality of departments, setting a tag for each department, establishing a tree structure tag of the users, and storing the tree structure tag into a central node in the storage cloud; (2) dividing data nodes in the storage cloud into a plurality of units, setting a tag for each unit, establishing a tree structure tag of a storage cloud system, and storing the tree structure tag into the central node of the storage cloud; (3) establishing a point-to-point incidence relation of the two tree structure tags to acquire a target unit security selection strategy in the data migration process of each department, and storing the target unit security selection strategy into the central node of the storage cloud; and (4) determining a target data node to be migrated in each data block to be migrated according to the target unit security selection strategy and then executing a migration command to perform migration by the central node. The method disclosed by the invention is easy in operation, and reduces the coupling degree between a customer and a provider.

Description

technical field [0001] The invention belongs to the security field of the storage cloud environment, and is mainly applied in the data migration process of the private storage cloud, and performs security management on the data to be migrated through a set of security rules and policies formulated. Background technique [0002] Storage cloud is an infrastructure based on distributed file system to realize storage cloud. [0003] First of all, the concept of storage cloud should be clarified. The so-called storage cloud, similar to cloud computing, refers to the collection of a large number of different types of storage devices in the network through application software to work together through cluster applications, grid technology or distributed file systems and other functions, and jointly provide data to the outside world. A service system for storage and business access functions. Therefore, the storage cloud technology includes the functional characteristics of the di...
