UEFI Secure Boot has roots in the Microsoft PC ecosystem, it was later adapted
to Linux, see Matthew Garrett's blog: http://mjg59.dreamwidth.org/9844.html
and Bootlin ELC 2018 slides:

Here is my intro to trusted boot, but Greg's explanation is more approachable
(it would make a good article!):

You could also watch some talks on boot integrity, e.g. Hudson, Smith:
