Nice glitchin! A reminder not to hide anything in your IoT device firmware.

Typically secure boot uses RSA or ECDSA so you just need to keep in fuses hash of public key which is not a secret. Not clear why bootrom uses AES256-ECB and SBK to authenticate bootloader while the app image is authenticated using ECDSA public key...

Excellent work! But let's be realistic. If someone is power glitching your microcontroller, you've already lost.

Do you plan to release the glitcher details (especially BOM / Schematic) ? To check what MOSFET you have used as I search the best MOSFET for next gen glitching board Requirements are fast (< 5ns pulse) and powerful (> 1A) MOSFET Vout 1.8V to 5V including ESD protections...

There are external solutions to store secrets, such as
@MicrochipTech ECC608 crypto authentication chips that may help? -
That won't provide secure boot. But perhaps it could be used for encrypting user data.
