【摘要】 访问控制是分布式应用的一个必要组成部分。由于访问控制机制的建立要求开发人员具有丰富的访问控制专业知识,所以建立有效的访问控制机制往往成为应用系统开发中的难点问题。论文研究并提出了一种基于组件的访问控制系统快速开发方法并建立了相应的开发工具。该工具采用面向组件的软件开发方法,支持组件化访问控制系统的动态策略定义、组件库管理和配置集成,能够根据用户选择的访问控制模型以及所定义的访问控制策略快速生成访问控制系统。所生成的访问控制系统可与应用系统无缝结合或部署到Web服务等分布式计算平台中,为应用系统提供所需的访问控制功能。更多还原

【Abstract】 Access control is a primary component of distributed systems. Since building an access control system needs the developers having plenty of professional access control knowledge,establishing an access control mechanism becomes a problem.This paper introduces a component-based access control developing tool which supports the fast development of an access control system. The tool adopts component-oriented software development method,which supports dynamic policy definition,component library management and component configuration-integration,and can build access control system with several policies rapidly,and make it more convenient on rapid development and deployment for the access control system.更多还原
