摘要
Access G rid是计算网格的一个扩展,用于支持在网格上进行组对组的大规模视频会议,也可用于协同工作、远程教学等多个领域。基于任务和角色的访问控制是最新的访问控制模型,它对传统访问控制进行了改进和扩充,能为Access G rid提供更高效的安全和管理服务。因此,Access G rid中基于任务和角色的访问控制是网格研究中的重要方向。
Access Gird is an expansion of computational gird, and is used to support large-scale video meeting and can also be used in fields such as collaborative work and remote education,etc. Task-role-based access control is the newest access control model,and it develop and extend some traditional access control models and can provide Access Grid with more efficient security and supervision services. So taskrole-based access control in the Access Grid is an important research direction of grid research.
