Ask HN: How to secure hardware? any existing solutions?

3 points by tornadofart 5y ago ↗ HN

I want to prevent counterfeit hardware from being used in a machine. The solution should be stand-alone,so independent from the existence of a network. I have a vague idea, but I'm not sure. You could have one microcontroller on each side exchanging encrypted messages over rfid, for instance.

How would I approach this? Do solutions already exist? I am by no means a security expert.

There's a company that recently went public. They specialize is verifying stuff like suppliers, products, etc. I don't remember the name.

If you verify the components and construction, then keep the machine in a secure location, that should be good. I know there are some bios-level protections that will not allow a boot if the hardware config changed too.

Would you also prevent counterfeit controllers?
