摘要
作为研究焦点的网格系统提供了一种受控的跨边界的资源共享的虚拟框架。对网格环境进行了分析,讨论了网格对信任管理的需求。在分析各种信任模型不足的基础上,基于网格具体的应用环境,并结合以PGP用户为中心的信任模型和SPKI授权证书机制各自的优势,提出了复合模式的网格信任授权模型,并完整设计了整个模型的可实现框架。
Grid computing systems that have been the focus of much research activities in recent years provide a virtual framework for controlled sharing of resources across institutional boundaries. Security and access control are major concern in any system that enables remote execution. The grid application environment is analyzed and a trust-based authorization model which integrates the advantages of role-based trust and authorization certificate is presented. An realizable architecture for the model is given.
