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.展开更多
