基于Web服务的网格应用系统安全模型

Web Services-based Grid Application System Security Model

分布式软件系统,特别是网络应用系统由于需要大量计算机节点的合作,因此该类系统的整体安全性比较难以控制。网格各计算节点之间需要进行接受来自网格系统的计算任务,节点之间的信任关系需要一种安全模型来进行统一处理。文章以基于SaaS模式的电子工程预算软件(SaasBudget)为研究对象,介绍了Web服务的安全问题以及网格平台下的安全解决方案,分析了目前网格平台常见安全性问题,提出了一种基于动态用户池的网格平台授权机制。

Distributed software systems, particularly network applications are required because of substantial cooperation between the computer nodes, so such systems as a whole more difficult to control security. Grid between the computing nodes required to accept the grid system from the calculation of mission, the trust relationship between nodes need a unified security model to deal with. In this paper, based on the SaaS model of software project estimates Electronics （Saas-Budget） as the research object, the introduction of Web Services security issues, as well as grid platform security solutions, analyze the current grid platform common security problem, a pool-based dynamic user authorization mechanisms mesh platform.
