  abstract =  { A key is updated in a first cryptographic device and an update
                message comprising information characterizing the updated
                key is sent from the first cryptographic device to a second
                cryptographic device. The update message as sent by the first
                cryptographic device is configured to permit the second cryptographic 
                device to detect compromise of the updated key by
                determining if an inconsistency is present in the corresponding 
                received update message based at least in part on that
                received update message and one or more previously-received 
                update messages. In an illustrative embodiment, the
                first cryptographic device comprises an authentication token
                and the second cryptographic device comprises an authentication server.
