Revocation schemes for delegated authorities

2002 (English)Conference paper (Refereed)
We have an existing framework for updating privileges and creating management structures by means of authority certificates. These are used both to create access-level permissions and to delegate authority to other agents. Here we extend the framework to support a richer set of revocation schemes. The discussion of revocation follows an existing classification in the literature based on three separate dimensions: resilience, propagation, and dominance. The first does not apply to this framework. The second is specified straightforwardly. The third can be encoded but raises a number of further questions for future investigation.
