How would that work? You want a government designed secure processor... why wouldn’t you figure that the reasons they are insecure now is because of gov involvement?
If you want an open source processor... that’s cool, and corporations can/are already do that.
Now... with any solution proposed, verify to me that the silicon as designed is really the silicon made, esp when talking about 7nm.
I don't care who produces the processor, but whoever does must be open, transparent, accountable, auditable, etc. as enumerated above.
Whichever group does this must not be guided by Lawyers who enter into secret agreements. That is, ALL legal aspects of this group must be open the public as well.
You raise an excellent point, which is "how is silicon verified as being the same silicon that was designed?".
Usually silicon is verified through tests at various levels of abstraction (electrical, signal, logical, single instruction, programs, etc.) but none of these directly verify that the silicon produced is the silicon designed.
So, you are correct, that's a very real problem that needs a very real solution in the future...
I don't know the practical reality of any company permitting that, but it's a good idea. Some future chip manufacturing group will hopefully do that.
Audits of any form at any time by any party should be permitted, rather than denied.
