服务计算安全模型研究

服务计算是一种新的分布式计算模式。在服务计算中,跨组织广域分布的资源共享对安全提出了极大的挑战,特别是资源的动态变化及应用安全需求的动态变化对安全提出的挑战。本文给出了服务计算的安全模型,分析了这种应用逻辑与安全策略分离的基于信任域的安全模型的主要思想和优点。该模型可为信息栅格安全构建提供一种有效的解决思路。

Research on Security Model of Services Computing

Services computing is a new paradigm of distributed computing.Security faces grand challenges in wide area distributed computing systems where distributed resources can be shared across institutional boundaries,especially when the dynamic changing security requirements of applications should be met on the fly.A security model of services computing is presented in this paper.Main idea and advantages of trust domain based security model are analyzed.The security model here provides an effective way to construct information grid security system.
