A Flexible Authorization Delegation Method in Multi-domain Environments Employing RBAC Policies

摘要：

In recent years,many researchers have noted that it will helpful to extend RBAC model to dynamic coalition environments. In this paper, we address the authorization issue in multi-domain environments where RBAC policies are employed.A flexible authorization delegation model is proposed,which combines RBAC model with delegation.The proposed model has powerful expressiveness,which supports these features as follows:multi-types of delegation,fine-grained delegation,temporal constraint,control on depth of delegation.In addition,this paper discusses other issues related with the proposed model,such as certificate storage,compliance checking and certificate revocation.
