Abstract

The invention relates to the technical field of cloud storage data access control, and discloses a cloud storage data access control system based on zero knowledge proof, the system comprising: a cloud storage server Si configured with a cloud storage database Di, cloud storage access control system software running on the cloud storage server Si. The system also comprises an access client Ui, andthe access client Ui is in communication connection with the cloud storage server Si; when an access client Ui sends a data access request to a cloud storage database Di of the cloud storage server Si, the cloud storage access control system of the cloud storage server Si verifies the identity of the access client Ui by adopting an access verification method based on zero knowledge proof, and only the access client Ui passing the identity verification is allowed to access the data in the cloud storage database Di of the cloud storage server Si. According to the invention, the technical problem that the identity of an access user cannot be subjected to security verification when the user sends an access request to a cloud storage server in existing conventional cloud storage access controlsystem is solved.

Description

technical field [0001] The invention relates to the technical field of cloud storage data access control, in particular to a cloud storage data access control system based on zero-knowledge proof. Background technique [0002] With the rapid development of computer technology and Internet applications, cloud storage services have been widely concerned and applied by virtue of their advantages of convenient use and cost saving. However, while cloud storage has many advantages, it also brings many new security risks. In the cloud storage system, the user's data is stored on the server of the cloud service provider (Cloud Service Provider, CSP), which is out of the absolute control of the user, and its security depends entirely on the system security of the CSP, the quality of the data administrator, etc. , which are uncontrollable factors for users. [0003] Since users cannot fully trust the CSP, the traditional access control method implemented by the CSP is no longer appl...
