Abstract:
1. A cryptographic device for securing data on a computer network comprising: a processor programmed to authenticate a plurality of users on the computer network for secure processing of a value bearing item, wherein the processor includes a state machine for determining a state corresponding to availability of one or more commands; a memory for storing security device transaction data for ensuring authenticity of a user, wherein the security device transaction data is related to the one of the plurality of users; a cryptographic engine for cryptographically protecting data; and an interface for communicating with the computer network; wherein the cryptographic device is located remotely from the plurality of users; wherein once the user is authenticated, the cryptographic device enters an operational state in which it continues to authenticate the user with respect to one or more transactions requested by the user, and wherein each security device transaction data includes an ascending register value, a descending register value, a respective cryptographic device ID, an indicium key certificate serial number, a licensing ZIP code, a key token for an indicium signing key, user secrets, a key for encrypting user secrets, date and time of last transaction, last challenge received from a respective client subsystem, an operational state of the respective device, expiration dates for keys, and a passphrase repetition list.
