Access control system based on cloud computing data security

Abstract

The invention discloses an access control system based on cloud computing data security, and belongs to the technical field of cloud computing. The system comprises an access strategy unit, a credibleauthorization unit and a user unit; the user unit comprises an inner domain user and an outer domain user; the access strategy unit is used for connecting the inner domain user with a cloud computingplatform, and the trusted authorization unit is used for connecting the external domain user and the cloud computing platform; the access strategy unit receives an access request of the internal domain user and verifies identity information of the internal domain user, so that data transmission between the internal domain user and the cloud computing platform is realized; and the trusted authorization unit encrypts an authorization instruction of the cloud computing platform, so that the external domain user obtains the access permission of the cloud computing platform by decrypting the authorization instruction. Users accessing the cloud computing platform are divided into inner domain users and outer domain users through the access strategy unit and the credible authorization unit, andthe access process is controlled to be safer and more reliable.

Description

technical field [0001] The invention relates to the technical field of cloud computing, in particular to an access control system based on cloud computing data security. Background technique [0002] With the development of cloud computing, cloud security has become an increasingly critical issue. In the cloud computing environment, users lose control over the data and computing placed in the cloud server, and have no control over whether the data is protected or the computing tasks are executed correctly. It cannot be determined, so it is necessary to design corresponding security mechanisms and architectures to protect the confidentiality, integrity, and availability of user data. How to implement a fine-grained access control mechanism for a large number of classified and hierarchical resources in cloud storage to ensure that data in cloud storage is not illegally accessed is a problem that needs to be solved urgently in cloud computing technology. [0003] Traditional c...

Problems solved by technology

[0004] The purpose of the present invention is to provide an access control system based on cloud computing data security in order to solve the problem that the above-mentioned cloud computing cannot guarantee the safe access of external domain users during access control, and there are potential safety hazards. The authorization unit has double protection for internal domain and external domain users, making data access more secure and reliable, and less vulnerable to malicious attacks
