基于时间和环境约束的四层访问控制模型研究
RESEARCH ON FOUR LAYER ACCESS CONTROL MODEL BASED ON TIME AND ENVIRONMENT CONSTRAINTS
摘要
Abstract
Aiming at solving the problem that the organization-based access control model (OB4LAC) cannot authorize users dynamically and timely in the complex government system,this paper proposed a time and environment constrained and organization-based access control model (TE-OB4LAC) by adding time and environment constraints to OB4LAC at the fine granularity constraint level.Firstly,it put forward to the concept of position behavior and role behavior by referring to the idea of behavior.Then it formally defined the model,and gave the access control authorization strategy and grant scheme.Finally,it analyzed and designed the general structure of the authorization management system based on TE-OB4LAC model and applied the TE-OB4LAC model into the e-government system.Experiments showed that the model was effective and scientific.关键词
