Embodiment

[0034] In this embodiment, an access control model based on HDFS cloud storage system is constructed, which adopts role-based access control technology, see figure 1 , the left side is the structure of the subject security label SSL, the right side is the structure of the object security label OSL, and the middle is the definition of access control rules and the authority determination algorithm.

[0035] In the HDFS-based cloud storage access control system, the rules of access control define two types of access control: read (r) and write (w), and each type is defined as follows:

[0036] Read (r): Have permission to view files in the cloud storage system or files under folders and subfolders.

[0037] Write (w): For files in the cloud storage system or files under folders and subfolders, have permissions to add files or folders, modify file content, rename files or folders, etc.

[0038] refer to figure 2 , in the authority determination algorithm, first ...

Abstract

The invention discloses a cloud storage access control method based on HDFS (Hadoop Distributed File System). The method comprises the steps of constructing an access control safety designing module, a permission judging algorithm module, a multiuser data isolating and sharing module and an HDFS based cloud storage system access control realization module, wherein an access control safety module is used for defining according to the traditional RBAC (Role-Based Access Control); the permission judging algorithm module is used for judging whether a subject has the permission to access to corresponding objects or not according to a defined algorithm, so as to realize safe access to cloud storage; a multiuser isolating and sharing design module is used for realizing the isolating and sharing of data of multiple users in an HDFS based cloud storage system; an HDFS based cloud storage system access control module is used for constructing Hadoop groups, deploying safety control modules and constructing a safety system architecture of the cloud storage system. The method is applied to an HDFS based cloud storage platform, and the isolating and sharing of the data of the multiple users can be effectively realized through analyzing the safety and performance of the cloud storage system.

Description

technical field [0001] The present invention relates to technical fields such as cloud storage, access control, and information security. Specifically, it is a cloud storage platform based on HDFS. According to the HDFS-based cloud storage access control method formulated in this paper, it is determined whether the user has access to specified data. Permissions to realize the isolation and sharing of data among multiple users. Background technique [0002] As a new business model, cloud computing has completely changed people's understanding of infrastructure, software distribution, development models, and data storage. Cloud computing adopts a pay-as-you-go model, and users can obtain nearly unlimited storage space and enterprise-level service quality from cloud service providers (Cloud Service Providers, CSPs). Therefore, it can help enterprises and governments reduce the cost overhead of data storage and data management. Cloud storage is a storage extension based on clo...
