Bypassing ESP32 Encrypted Secure Boot
That's a pretty nice write-up, and continues to show why hardened hardware is needed, not just software, if you actually have secrets to protect.One thing that struck me is "After running these experiments for more than a day, resulting in more than 1 million experiments, we did not observe any successful glitch…"That's like 100ms per test. Are those devices that fast to put into uart mode and reset and wait for the result? Were they running this with multiple devices in parallel?
