Abstract

The invention discloses an attribute based access control method and system. The method is implemented through steps as follows: granting and revocation of subject attribute information and a specific subject; collection of environmental attribute information; creation of a strategy; implementation of the strategy; acquisition of running state attributes; determination of a unified data demand response mode of all parts. Access control is realized through control of subjective and objective attribute information and the environmental attribute information, and a series of problems of poor safety, large authority management difficulty, extension difficulty and the like of traditional access control can be solved, so that efficient access control is realized.

Description

technical field [0001] The invention belongs to the technical field of access control, and more specifically relates to an attribute-based access control method and system. Background technique [0002] Access control technology is mainly used to protect data shared on large systems and prevent access by unauthorized and illegal users. With the development of information technology, especially the rapid development of the Internet, access control technology has also been greatly developed. [0003] According to different authorization methods, access control methods can be divided into: discretionary access control (Discretionary Access Control, DAC), mandatory access control (Mandatory Access Control, MAC) and role-based access control (Role-Based Access Control, RBAC). Autonomous access control is managed by the owner of the object, and the owner himself decides whether to grant his object access right or part of the access right to other subjects. Selectively share his ...
