摘要： 电子政务涉及到党政部门的内部信息资源,同时又要实现与民众间的双向交流,实现资源开放。从整体的角度看,整个安全体系结构具有多层次、大规模、复杂交互的分布式结构。电子政务需要一种大规模应用环境下具有高安全性和一定开放性的访问控制体系以满足安全需求。该文阐述了基于角色控制的ARBAC97模型在电子政务中的应用,并描述了如何利用权限管理基础设施来实现该访问控制模型。

Abstract: The e-government involves both the internal information resources for the government and the public resources for exchanges. From the integer point of the view, the security architecture of the e-government is a large-scale multilevel distributed architecture. Therefore it is essential to look for a access control solution satisfying the need of the e-government application. This paper discusses the application of the Arbac97 model in e-government and presents a framework using PMI (Privilege Management Infrastructures) to implement role based access controls.
