Does this have any implications for Secure Enclave like chips?

• sowbug 7y ago
  I have no expertise on this subject, but here goes. First, I don't think the technique can see electrical charges, which is how any chip stores volatile state. Second, if such chips rely on security by obscurity -- and judging from the NDAs typically required to get any official information about them, I'd say it's part of their defense in depth -- then that security would now be weaker. Finally, this technique would arguably enhance security if independent labs were now able to verify that a chip is devoid of back doors and implementation errors.
