Today, many embedded projects run on x86 platforms, and often end users are
concerned about security. The term Root of Trust matters a lot here. One of its
components in the case of x86 is UEFI Secure Boot. It is a standard defined in
UEFI that allows for trusted key verification of images loaded by UEFI BIOS.
Using the publicly available layers, I would like to present what UEFI Secure
Boot is and how to integrate it into Yocto Project.
