| 摘要: |
| 针对政务信息资源使用控制的主体关系特征和动态性需求，提出基于UCON_ABC改进模型的政务信息资源动态使用控制方法，方法将基于角色的访问控制思想与动态使用控制方法相结合，改进UCON_ABC模型；在此基础上，基于UCON_ABC的授权、责任、条件等使用控制策略，构建了面向政务信息资源动态使用控制的预先决策方案；通过在政务信息资源使用控制的一个典型场景中应用改进后的UCON_ABC模型，并对比典型的传统使用控制方法，验证基于UCON_ABC改进模型的政务信息资源使用控制方法的优势；结果表明：基于角色的UCON_ABC改进模型，可以降低UCON_ABC模型的管理难度，并能够更好地适应政务信息资源使用控制的动态性需求。 |

| Abstract: |
| According to the characteristics of the subject relationship and the dynamic demand of the usage control of government information resources, a control method of the dynamic usage of government information resources based on the improved UCON_ABC model is proposed. This method combines role based access control with dynamic usage control to improve the UCON_ABC model. Furthermore, we design a pre decision model for the dynamic usage control of government information resources based on the authorization, responsibility, condition and other usage control strategies of UCON_ABC. Based on the improved UCON_ABC model in a typical scenario of the usage control of government information resources, and by comparing with the typical traditional usage control methods, the advantages of the improved UCON_ABC model are verified. The results show that the improved model can reduce the management difficulty of UCON ABC model, and better adapt to the dynamic needs of the usage control of government information resources. |
