Abstract
A Verified unit (VU) communicates with an Authenticating Unit (AU). The VU only provides the AU with the user'"'"'s public key via RSA technology known in the art. The AU sends a character string to the VU requiring the VU to generate a digital signature which is sent to an Authority server (AS) to authenticate the digital signature information provided to the AU by the VU. If the AS authenticates the information it informs the AU and the AU will provide the VU'"'"'s requested data to the VU.
