The Federal Government is not going to allow a manufacturer to sell something they can’t hack. That is just a fact in 2013.
It’s technologically impossible. The IT Security industry RELIES on the defensible nature of technology. It’s why large corporations like Google are getting nervous with the Feds asking for their salt and hash algorithms.
Realize if ANY of the Class A certification authorities gave into the government, the ENTIRE cryptography industry would crumble. There’s a reason certification authorities pride themselves on trust. If any of them are cracked or hacked, they lose everything. Entrust, Thawte, Verisign: they ALL rely on the stability of their encryption algorithms.
I’ve studied cryptography for over a decade. The conspiracy theorists may be partially correct with pre-configured chipsets such as those in Cisco network hardware, but when it comes to certificates, VPN, and things like TPMs, the managers and “key holders” MUST be trustworthy or their entire network of trust collapses.
And the PLA is not going to allow a Chinese fab to make chips without a back door, either.
