Abstract | Delegation certificates (e.g. SPKI[7]) support the decentralized management of access rights in organizations without the need for a centralized server to mediate every delegation operation. However, it does not allow the access rights to be delegated in a flexible way. For instance, a user cannot be granted the authorization to perform delegation of a permission without granting himself/herself the authorization to exercise the associated permission at the same time. In this paper, we propose an improved delegation model, where the various users in a delegation chain may perform supervision on the delegate to exercise the delegated permission. We also describe the way to support the model using SPKI as an example. |
