Abstract
Providing revocation status of at least one associated credential includes providing a primary credential that is at least initially independent of the associated credential, binding the at least one associated credential to the primary credential, and deeming the at least one associated credential to be revoked if the primary credential is revoked. Providing revocation status of at least one associated credential may also include deeming the at least one associated credential to be not revoked if the primary credential is not revoked. Binding may be independent of the contents of the credentials and may be independent of whether any of the credentials authenticate any other ones of the credentials. The at least one associated credential may be provided on an integrated circuit card (ICC). The ICC may be part of a mobile phone or a smart card.
