Usage Control is a generalization of access control to cover obligations, conditions, continuity and mutability. However, the delegation component isn’t discussed to the full. In this paper, an improved scheme for delegation based on the usage control model is proposed. The new model is not just expanding the UCONABC Model simply by increasing the delegation component as earlier literatures [10]. By analyzing the cross domain problem in the e-government environment, the delegation is proposed naturally and discussed deeply. The new model and the delegation characteristics are described from the different viewpoints, and the corresponding monitor and architecture are also proposed at last.
