1. A method comprising the steps of:
providing a white box having an associated cryptographic function and an associated key;
the white box transforming each of the the cryptographic function and the key, thereby providing a transformed cryptographic function and a transformed cryptographic key;
providing a communications channel between the white box and a crypto token coupled with the white box, the white box authenticated to the crypto token using the transformed cryptographic key;
periodically determining presence of the crypto token; and,
providing a verifiable message, responsive to the presence of the crypto token, thereby initiating a service.
