Abstract
Techniques are provided for security-aware split-server passcode verification for one-time authentication tokens. An exemplary method comprises receiving an authentication passcode generated by a token; and processing the received authentication passcode using at least a first authentication server and a second authentication server. The received authentication passcode is based on a protocode and/or embedded auxiliary information. The embedded auxiliary information comprising a silent alarm and/or a drifting key is extracted from the received authentication passcode. In another exemplary method, the received authentication passcode is processed using a single processing device to extract the embedded auxiliary information comprising one or more of a silent alarm and a drifting key. Another exemplary aspect addresses the processing of an authentication outcome from at least one authentication processing device and providing access to a protected resource based on the authentication outcome and a predefined access policy.
