摘要
网格要实现分布资源的共享,必须构建新的安全体系,制定更高要求的安全机制。通过分析网格计算的安全特性和安全策略,研究了网格计算的安全体系结构,讨论了结构中的主要技术和用户任务的安全认证过程。介绍了Globus Toolkit3(GT3)中安全机制的实现,探讨了Globus Toolkit3为体现OGSA思想对安全机制和任务分配流程的改进。
New security system and higher-standard security mechanism of grid should be constructed in order to real- ize the share of resources distribution in Internet. By analyzing security characteristics and policies of grid computing, we have researched security infrastructure of grid computing,discussed the key technology in the security infrastruc- ture,and the security certification procedure of the user's task. This paper also introduces the realization of security system in Globus Toolkit 3(GT3),discusses the improvement of the safe system and task allocation procedure of Globus Toolkit 3 based on OGSA.
