网格计算安全模型的研究

网格计算是一种新型的计算模式,具有数据处理能力强和运行成本低的特点。近年来,有关网格计算系统的安全性设计越发受到关注,但现有的网络安全技术在处理复杂的、动态的网格计算系统时,在访问控制、权限授予等环节的效果并不理想。首先分析了网格计算系统的安全性需求,其次研究并借鉴了现有颇具代表性的网络安全架构,最后我们从网格安全设计和实现的角度,对网格计算系统提出一种新的安全体系结构模型,并深入讨论了网格计算系统中各实体间交互时所采取的相应安全策略。

Research on Security Model of Grid Computing

Grid Computing is a new style computing pattern with super capacity of data processing and much lower hardware cost. In recent years, more and more attention is put to the security design of grid computing systems. Unfortunately, most classic methods fail to do well in authority management, which is of great importance to such services as access control and so on. This paper researches and uses some existing security framework as a source of reference based on deep analysis of the security demand of grid co...
