Overview of UEFI Secure Boot¶
Secure Boot is an optional capability of UEFI firmware.
Secure Boot is a technology where the system firmware checks that the system boot loader is signed with a cryptographic key authorized by a database contained in the firmware or a security device.
StarlingX’s implementation of Secure Boot also validates the signature of the second-stage boot loader, the kernel, and kernel modules.
StarlingX’s public key, for programming in the hardware’s Secure Boot database, can be found in the StarlingX ISO.
