ABSTRACT:
Cryptographic hardware is provided that is disabled at the time of shipment and that is selectively enabled in a trusted fashion using methods and interfaces that may be controlled by and governed by government policy in strict compliance with existing and future legislation. A given cryptographic algorithm is disabled/enabled at several points, referred to as Touch Points, and referred to collectively as Touch Point Logic. Because attributes of each touch point are satisfied by providing data that are referred to as Touch Point Data, manufactures are allowed to include disabled cryptographic hardware in their products and governments are provided with the ability to enable this cryptographic hardware only in compliance with governing legislation.
