With the development of a new generation of information technology,all aspects of people’s work and life are becoming more and more closely related to information systems,and the interaction of information resources is becoming more and more frequent,and the information security problems that come with it are becoming more and more serious.Among the many security technologies and services,access control technology is an indispensable part of all information systems,and detailed requirements for access control are made in the document "Basic Requirements for Classified Protection of Information Security Technology Network Security" published in 2019,and more and more attention is paid to access control technology.In the application scenarios of super business systems,there are problems of multi-user and multi-business.The role-based access control models are prone to role explosion,and cannot achieve dynamic fine-grained access control authorization,user privacy is also not well protected.The attribute-based access control models can achieve dynamic access control authorization,but in complex resource situations,there may be the problem of redundancy of access control policies.In order to address the above issues,the research content of this paper is proposed to achieve secure and fast access control authorization in super business systems.This paper elaborates on the research achievements and current status of access control technology both domestically and internationally through literature research,summarizes the development history of this technology,analyzes the increasingly complex security access control requirements of information systems,and introduces the development and characteristics of super business systems.This paper explains and verifies the BE-BAC model from both theoretical analysis and experimental verification.It compares and analyzes it with other models in theory,designs application scenarios to verify the usability and performance of the proposed model,and finally applies the proposed model in practice.The results show that the proposed business entity-based access control model has good performance in the environment of super business systems,It also has a certain enlightening effect on future research. |
