Abstract
A recovery mechanism is provided for split-server passcode verification systems. An exemplary token-centric recovery scheme comprises at least one token and a plurality of authentication servers, comprises the steps of: determining that a first one of the plurality of authentication servers is unavailable; applying an authentication mechanism to a message requesting the token to change to a new split-state mode; and sending the authenticated message to the token. The authentication mechanism comprises, for example, a relying party signing the message using a next passcode of the new split-state mode. The new split-state mode comprises, for example, a single server passcode verification and wherein the next passcode of the new split-state mode comprises a next passcode of the single server. A client optionally changes to the new split-state mode after successfully verifying the authentication mechanism.
