ABSTRACT:
Determining access includes determining if particular credentials/proofs indicate that access is allowed, determining if there is additional data associated with the credentials/proofs, wherein the additional data is separate from the credentials/proofs, and, if the particular credentials/proofs indicate that access is allowed and if there is additional data associated with the particular credentials/proofs, then deciding whether to deny access according to information provided by the additional data. The credentials/proofs may be in one part or in separate parts. There may be a first administration entity that generates the credentials and other administration entities that generate proofs. The first administration entity may also generate proofs or may not generate proofs. The credentials may correspond to a digital certificate that includes a final value that is a result of applying a one way function to a first one of the proofs.
