URP中授权管理系统的设计与实现

PMI是一个新的信息保护基础设施,能够与PKI和目录服务紧密集成。PMI作为一个基础设施,能够系统地建立起对合法用户的特定授权。PMI通过结合授权管理系统和身份认证系统消除了PKI的弱点,提供将PKI集成到商业计算环境的应用模型,而不只是将PKI的应用限制在用户安全解决方案上,因此,基于PMI的授权应用前景很好。文中介绍数字校园及URP(大学资源计划)的概念,分析PMI技术的授权管理模式的特点,重点叙述PMI与PKI,URP应用系统的逻辑关系,并设计与实现URP中的授权管理系统。

Design and Implementation of Authorization Management System in URP

PMI is a new infrastructure of protected information based on PKI,can integrate compactly with PKI and LDAP and can establish systemically special authorization of legitimate users. PMI provides application model in commercial calculation environment with integrated PMI,not make the application of PKI restricted in user's security solution only. So that,application of PMI in authority is wide. In this paper,the conception of digital campus and University Resource Plan is introduced,then give an analysis of authority management pattern of PMI.And primarily introduce the logic relation between PMI and PKI,application system of URP,then design and implementation of authority management in URP are presented.
