Abstract
Object management is facilitated by signing objects with credentials and through noting and/or using an association between the signed objects and the signing credentials. In an exemplary method implementation, actions include: signing an object with a credential to produce a signed object and noting an association between an object identifier that represents the signed object and the credential. In another exemplary method implementation, actions include: receiving a revocation request for a signed object; accessing a database at an entry for the signed object to retrieve an associated credential, the associated credential having been used to sign an object to produce the signed object; and causing the associated credential to be revoked. In an exemplary electronically-accessible media implementation, a data structure thereof includes: at least one entry that associates a credential with an object identifier, the object identifier representing a signed object that was signed by the credential.
