授权管理基础设施技术在企业权限管理中的应用

PMI（授权管理基础设施）技术是一种新型的信息保护基础设施，它的目标是向应用系统提供相关的授权服务管理，实现与实际应用处理模式相对应的、与具体应用系统的开发和管理无关的访问控制机制。讨论了在分布式环境中利用PMI技术完成权限管理，及其相对于现有的嵌入于应用系统中的授权管理的优越性，并论述了实现的可能性，提出了实现的途径和方案。

Application of PMI technology in enterprise's privilege management

The PMI has been recommended as a new information protection infrastructure, to provide privilege management service and to get an access control mechanism which is fit for most of actual transact patterns and free of the development and management of concrete applications. The advantages of using PMI technology instead of applicationembedded privilege management as before were introduced in distributed Web applications. The possibility of its realization was discussed and the scheme of its realization was proposed.
