【摘要】 在讨论网格安全性需求的基础上提出一种可伸缩、可扩展的访问控制安全策略与相应的安全模型,并提出一种灵活的访问控制安全策略,它支持网格计算环境固有的动态性、可伸缩性和可扩展性。相应的访问控制安全模型基于该策略进行设计,通过基于XML的查询请求/断言应答语言SAML和可扩展访问控制语言XACML来支持身份认证和访问控制。更多还原

【Abstract】 Based on the security demands of grid,the paper proposes a retracted and extensible security strategy of access control as well as the corresponding security model.It also presents a flexible access control security policy,which supports the inherent dynamics,flexibility and expansibility of grid computing environment.Based on the strategy design,the corresponding access control security model is able to support identity authentication and access control through XML-based inquiring request /assertive response language SAML and extensible access control language XACML.更多还原
