Abstract

It is a challenge to integrate and share resources securely across multiple autonomous administrative domains environment. We introduce the community-based model of vega enterprise information grid and its operation mechanism. The individuals and/or institutes forming different communities can not only implement diverse policies and autonomous management of resource sharing without any impact on the other communities, but also achieve a globally shared goal. Based on the model, the access control technique, including framework and uniform formalizing, is presented in detail. The static or dynamic role binding is used for entitling user's request for accessing resources within or across communities, which ensures a globally unified view for user. A prototype describes how these techniques are useful in building an enterprise information grid. The evaluation and future continuing works are presented in the conclusion.
基于社区的信息网格模型与访问控制
如何跨多个自治管理域环境安全地集成和共享资源是一个挑战。介绍了基于社区的织女星企业信息网格模型及其运行机制。形成不同社区的个人和/或机构不仅可以在不影响其他社区的情况下实施多样化的政策和自主管理资源共享,而且可以实现全球共享的目标。在此基础上,详细介绍了访问控制技术,包括框架和统一形式化。静态或动态角色绑定用于授权用户访问社区内或跨社区资源的请求,从而确保用户的全局统一视图。原型描述了这些技术如何在构建企业信息网格时发挥作用。结语部分提出了本文的评价和后续工作。
