中文摘要：

这篇文章为解决建议扩大基于角色的存取控制(RBAC ) 模型动态并且多在格子计算的域问题，对模型的提出的描述被提供了。上下文的介绍和 context-to-role andcontext-to-permission 的印射的关系帮助模型在格子环境适应动态性质。由授权代理人服务的 multidomainrole 继承关系认识到多在自治领域之中的领域授权。功能为在建立期间解决角色继承冲突被建议了多领域角色继承关系。

英文摘要：

This article proposes the extended role-based access control （RBAC） model /br solving dynamic and multidomain problems in grid computing, The formulated description of the model has been provided. The introduction of context and the mapping relations of context-to-role and context-to-permission help the model adapt to dynamic property in grid environment. The multidomain role inheritance relation by the authorization agent service realizes the multidomain authorization amongst the autonomy domain. A function has been proposed for solving the role inheritance conflict during the establishment of the multidomain role inheritance relation.
