基于Globus的网格安全机制研究及扩展

随着网格应用的发展,网格安全问题日渐突出。为解决此问题,Globus项目组作了大量工作。讨论网格环境下的安全问题,分析Globus的安全机制,结合虚拟组织技术和基于角色的访问控制方法,探讨基于Globus安全基础设施的扩展的安全技术——社区授权服务机制,并对网格环境下的安全技术的基本问题进行了总结。

Research and extension on grid security mechanism based on Globus

With the development of grid application,the problem of grid security is becoming more and more serious.To solve this problem,Globus project team made a large work.In this paper,the safety of the grid environment is discussed.Then the security mechanism combined with the Globus virtual organization technology and role based access control method is analysed.The Globus security infrastructure based on the expansion of the security technology-the community authorization service is discussed.At last,the basic problem of the safety technology in grid environment is summarized.
