Attribute-based access control method in grid computing
网格计算中一种基于属性的访问控制方法

In order to satisfy the grid's need for dynamic and fine-grained authorization policy,this paper presented a model named Grid_ABAC for grid computing.This model based on the layed structure of grid resources and the current ABAC model.Also designed implementation architecture of Grid_ABAC with XACML and used it in GT4 platform.At last,made a test in Globus platform.The result shows that the authorization result is identical to the expected result and the time cost doesn't increased apparently with the incre...
