Access control system and access control method between public cloud and private cloud

Abstract

The invention discloses an access control system and an access control method between a public cloud and a private cloud. The access control system includes a private cloud control module at a private cloud end, and a public cloud control module at a public cloud end. The private cloud control module comprises an inter-cloud data exchange module and a user access control module. The inter-cloud data exchange module is respectively connected with the user access control module and the public cloud control module through a network. The access control method combines role-based access control and attribute-based access control, an attribute-based access control mode is adopted in the private cloud, and a role-based access control mode is adopted when the private cloud accesses the public cloud. Due to the fact that the access control system limits the access right of users of the private cloud to resources or services of the public cloud, the access control system has the advantages of being quite high in inter-cloud data exchange safety.

Description

technical field [0001] The invention belongs to the field of computer security access, in particular to an access control system and method between a public cloud and a private cloud. Background technique [0002] For today's IT era, cloud computing represents the core competitiveness of the future information technology field, whether it is cloud computing researchers, various IT companies, or even governments around the world are very concerned about it. With its advantages of convenience, economy, and high scalability, cloud computing has attracted the attention of more and more enterprises, freeing them from the heavy pressure of IT infrastructure management and maintenance, and focusing more on their core business development.
