Title: Hardware level security
Post by: Elwar on September 18, 2012, 12:51:55 PM
We can all get very paranoid and do everything we can at the software level to secure our wallets and everything else related to security.

But if someone manipulates your hardware, you would likely never know.

Are there any ways to counter something like this occurring? Someone at Intel could stick a private key reader into the chip and everyone who uses that chip from then on would be screwed.
Or someone could add a chip to the computers as they sit in a huge server room. Or even someone at UPS or FedEx.

I only have indirect knowledge of such attacks but am wondering if others have considered this.

Sure, use multisig and store the keys on two different types of hardware (e.g. cell phone and computer).

Doesn't even need to be an Intel engineer. If a rootkit loads before an OS, then it'll be able to do the same things.

Is multisig now available in the satoshi client?
