摘　　要：网格将分散的资源聚合在一起,形成更高层次的分布式资源共享环境,安全问题一直以来都是网格环境中考虑的一个重要问题。研究并设计了网格服务系统的安全体系结构,分析了网格服务系统的特点及面临的安全问题,讨论了安全体系中涉及的技术手段,通过本地及域级用户映射机制和资源自描述的安全方案,实现了较为灵活的网格服务系统安全体系。Distributed resources are aggregated by grid to form a high level sharing environment of distributed resources. Security is an important issue that grid environment should take into account. The characteristics and security problems of grid service system are analyzed, technologies related to security architecture are discussed. A flexible security architecture of grid service system is realized via local and domain-level user mapping mechanism and self-described security policies of resources. Finally, the process of user login and resource accessing of the security architecture is described.
