网格环境的安全需求及解决方案初步分析

Security requirement of grid environment and its solution

网格环境建构在现有的互连网络之上,涉及大量资源的共享与协商使用。而这些资源可能位于多个异构的、地理位置分布的计算机系统上,资源的类别也完全有可能千差万别。虚拟组织涵盖多个分布的个体和组织,允许用户和资源的动态加入和退出。网格环境的这种动态、异构特性引入了具有相当挑战性的网格安全课题。这里分析了网格环境面临的安全挑战以及网格开发工具包Globus Toolkits中GSI的一些关键技术和处理方案。

The grid computation building on the existing Internet is concerned with the share and coordinated use of diverse resources in the distributed ＂virtual organizations （Vos）＂. The Vos consists of the groups of individuals and associated organizations and services. The dynamic and multi-institutional nature of the grid environment introduces the challenging security issues. These security requirements within the grid environment are simply analyzed and the solution policy within the GSI of the Globus Toolkits.
