Embodiment Construction

[0018] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] In order to solve the problems existing in the prior art, the access control system and the access control method of the cloud storage service platform proposed by the present invention are based on the weight attribute encryption mechanism, adopt multi-organization attribute-based encryption technology, and store the user data to be uploaded after encryption to the cloud storage service platform.

[0020] figure 1 It is the structure of the access control system of the cloud storage service platform provided by the present invention. For the convenience of description, only the parts relat...

Abstract

The invention belongs to the field of cloud service information safety, and provides an access control system for a cloud store service platform and an access control method thereof. The system and method are based on a weight attribute encryption mechanism, adopt a multi-mechanism attribute based encryption technique, encrypt the data and then store in the cloud store service platform, thereby improving the safety of cloud store service. In addition, as the attribute and weight are combined, hierarchical management of user attributes is realized, different levels of users with the same attribute have different access authorities, and more flexible and subtle access control is realized. Furthermore, the system and method adopt the multi-mechanism attribute based encryption technique, thereby preventing a single authentication center from having excessively centralized authority, and further improving safety of data store. The system and method are particularly suitable for being deployed on an open storage service (OSS) platform, can effectively guarantee confidentiality of data stored in the OSS platform by users, and can perform fine grit access control on a data sharing range.

Description

technical field [0001] The invention belongs to the field of cloud service information security, and in particular relates to an access control system of a cloud storage service platform and an access control method thereof. Background technique [0002] In the cloud storage service platform, due to the use of remote data hosting technology, the cloud service provider is the physical owner of the data, but it is not in the same trust domain as the data owner. Cloud storage service providers manage multiple users and their resources. When users access other user resources across borders, they need to adopt certain access control policies to control access to data and services. But in reality, since the cloud storage service platform adopts virtualized storage technology, the cloud storage service is loosely coupled with the underlying hardware environment, and there is no fixed security boundary between the data of different users, which increases the Difficulty in implement...
