Claim Text:
1. A method for configuring a one-time authentication token, comprising the steps of: providing a plurality of selectively enabled token features in said configurable one-time authentication token, wherein said plurality of selectively enabled token features comprise at least two of a split-server passcode verification feature, a silent alarms feature, a drifting keys feature, a forward-secure pseudorandom number generation feature, a token randomness generation feature used for the generation of passcodes, a randomized state transitions feature, a data-transaction signing feature, an auxiliary channel feature and a time synchronization feature used to maintain synchronization between said one-time authentication token and an authentication server; obtaining a configuration selection of at least said plurality of said selectively enabled token features; and configuring said one-time authentication token based on said configuration selection to enable said selected token features in said one-time authentication token, wherein said configuration selection must always enable said forward-secure pseudorandom number generation feature for said one-time authentication token and at least one additional selected token feature, wherein said time synchronization feature communicates that a forward clock attack has occurred.
