【摘要】 文章首先分析了网格计算系统涉及的安全问题,阐述了对其安全机制的考虑。经过剖析当今典型系统Globus实现的网格安全架构解决方案GSI(Grid Security Infrastructure),在借鉴其长处的基础上,以资源映射与管理为切入点提出了较为灵活全面的网格计算系统安全体系结构模型。然后基于该安全体系结构模型在Globus环境下设计和实现了一个安全方案。文章最后介绍了将要开展的工作。更多还原

【Abstract】 This paper analyzes security problems existing in Grid Computing System,describes the consideration of security mechanism of Grid Computing System. A more comprehensive and flexible security architecture model of Grid Computing System has been proposed on basis of explosion of GSI(Grid Security Infrastructure) adopted by Globus. Compared with GSI,resource mapping and management are characteristic of the new model. A security schema then has been brought into effect under the Globus environment based on this security architecture model. Future works are introduced in the end.更多还原
