随着面向服务的网格技术的发展和应用,如何解决访问资源的授权成为一个关键性问题。本文通过对当前授权系统的概述和分析,设计了一种面向服务的网格授权系统(service-oriented authorization system for grid,SOA)。通过设计网格平台的集中授权服务,并与Globus Toolkit 4进行验证测试,显示SOA系统性能良好,能够为网格应用提供细粒度的、灵活的基于属性的授权保护。
With the rapid development and application of service-oriented Grid technologies, how to make resource authorization has become a critical issue. In this paper, we summary and analyze the related authorization systems, and then a serviceoriented authorization system named SOA is designed. An authorization service for Grid middleware is implemented, and some tests integrated with GT4 are conducted. The experimental results show our methods are efficiency and practical.
