Abstract
Server methods and apparatus are provided for processing passcodes generated by configurable one-time authentication tokens. An authentication server is configured to process an original passcode generated by a configurable one-time authentication token by configuring the authentication server to have a server configuration that is compatible with a selected configuration of the configurable one-time authentication token; receiving a candidate passcode based on the original passcode generated by the configurable one-time authentication token; and processing the Is candidate passcode based on the server configuration. The selected configuration of the configurable one-time authentication token must always enable a forward-secure pseudorandom number generation feature for the one-time authentication token and at least one additional selected token feature.
