摘要: 首先分析了电子政务的协同性特点,阐述了多域协同工作环境下电子政务系统面临的安全问题。借鉴基于角色的访问控制思想,提出了基于用户、角色和权限分配的电子政务访问控制模型,通过引入权限期和作用域的概念,建立了角色和权限分配机制,描述了模型的运行机制,并就发生访问冲突情况下的调停问题给出了算法实现思想。最后以一项典型的政务活动—文件流转会签为例,具体说明了模型的使用方法,有效地解决了多域环境下电子政务的系统安全和信息保密问题。

Abstract: This paper first analyzed the collaborative characteristics of cgovernment, described the security problem e-government system facing in the environment of multi-domain collaborative work. ho draw on the experience of role based access control thought, we advanced the access control model of e-government based on the distribution of user,role and authority, through introducing the concept of authority period and effect scope, we established the distribution mechanism of role and authority, described the operating mechanism of model, and gave the thought of algorithm realizalion for conciliation problem in the situation of occurring access violation. Finally we gave a typical administrative activitics-documents circulation countersigning for example, concretely specified the application method of model, effectively solved the problem of system security and information confidentiality for e-- government in the multi-domain environ- mcnt.
