Secure boot question

Postby jojojijijojo » Thu Jan 27, 2022 1:35 pm

Hi,

I understand that with secure boot, it prevents other binary images from booting into my device, but what about if I want my binary images protected against running on clone hardware? Does secure boot protect against that?

No if someone has your binary image they can run it on other hardware that's why you want to prevent them from obtaining it using flash encryption and secure ota.

Thanks, that's what I figured, flash encryption is necessary in this case.
