In the widely used public-key cryptography, creation of keys can be done on the local computer and the creator has complete control over who has access to it, and consequentially their own security policies. In some proposed encryption-decryption chips, a private/public key is permanently embedded into the hardware when it is manufactured, and hardware manufacturers would have the opportunity to record the key without leaving evidence of doing so. With this key it would be possible to have access to data encrypted with it, and to authenticate as it. It is trivial for a manufacturer to give a copy of this key to the government or the software manufacturers, as the platform must go through steps so that it works with authenticated software.
