Abstract: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 increase of test scope. Grid_ABAC model is valid in grid platform. ......
