A Distributed Access Control Model and Access Method

Abstract

The invention discloses a distributed access control model and access method. The access control subject sends access request information, and the neighbor nodes of the access control subject judge whether they are the access control object according to the access request information; if so, judge the access control subject's Whether the access request complies with its own access control strategy, if so, provide corresponding access content and operations; The control strategy judges whether the access control subject in this access request has permission to access the access control object in this access request; if it has permission, it forwards the access request to its neighbor nodes and repeats the above operations; if not, then Return a rejection message. The access control strategy of the present invention adopts a distributed management method, so that each node in the network that has an access relationship with it jointly manages the access control strategy of the entire network.

Description

technical field [0001] The invention relates to the technical field of computer security, in particular to a distributed access control model and an access method. The model utilizes distributed management and authorization to realize more secure and smooth access control in complex networks. Background technique [0002] Computer science and technology is at the core of information technology. With the rapid development and popularization of communication technology, information technology and network technology, computer hardware, operating system, network security, database and other technologies have promoted the continuous transformation of information technology. While the open network brings great convenience and value to people, it also puts forward higher requirements for network security. Especially in terms of controlling user access to information and resources, it is necessary to ensure that the maximum sharing of network information and resources is realized u...

Problems solved by technology

As information storage and access become increasingly distributed, the existing object-centric centralized authorization access control can no longer meet the security and robustness requirements of current complex network access control.

In addition, the traditional centralized authorization access control model has defects such as low adaptability, single deployment and application methods, and easy to become the target of attackers, which cannot meet the security requirements of dynamic heterogeneous open networks for access control.
