网格是一种新兴的分布式计算技术,它能够在动态变化的由多个机构组成的虚拟组织中,协调资源共享和共同解决问题。网格是由多个资源提供机构为了一个共同的目标,将地理上分隔的资源进行聚合,纳入到一个统一的管理域,并提供透明的视图。网格能够充分利用这些资源,相互合作来解决一些单个组织不能完成的高度分布的问题。该文讲述了网格及其相关的安全问题,讨论在网格中出现的具体的网络安全问题。最后将展示在网格方面的一些进展并对这项技术提出展望。
Grid is an emerging distributed computing technology that can coordinate resource sharing and solve problems together in a dynamically changing virtual organization of multiple agencies. Grids are aggregated by geographically separated resources by multiple resource providers for a common purpose, integrated into a single administrative domain, and provided with a transparent view. Grids can take full advantage of these resources and work together to solve highly distributed problems that individual organizations can not complete. This article describes the grid and its related security issues and discusses specific network security issues that arise in the grid. Finally, we will show some progress on the grid and put forward the prospect of this technology.
