摘要 网格为人们整合异构、分布的资源提供便利的同时,也带来了使用资源时访问控制的问题。网格环境下并没有形成一个成熟、完善的访问控制模型,而传统的基于角色的访问控制模型(RBAC)也并不完全适合于动态、异构的网格环境。结合“科学数据网格”系统中访问控制的研究,提出了一个扩展RBAC的动态访问控制模型。最后介绍了这个动态访问控制模型系统的实现。 Although grid provides a convenient way for integrating heterogeneous,distributed resource,it also incurs the resource access control problem at the same time.Since a universal grid access control model does not exist and the traditional RBAC model is not fit for the dynamic,heterogeneous grid environment,we present a dynamic access control model which is extended from RBAC model.In the end,an implementation of this model will be introduced.
