What is UEFI Secure Boot?
UEFI Secure Boot is a security feature implemented in the Unified Extensible Firmware Interface (UEFI) firmware, which is a modern replacement for the traditional BIOS firmware found in most computers. It aims to protect the boot process from malware attacks by ensuring that only trusted firmware, operating system kernels, and drivers are loaded during system startup.

Secure Boot relies on a set of cryptographic keys, including a Platform Key (PK) and one or more Key Exchange Keys (KEKs), which are used to verify the signatures of boot components. These keys are managed by the system firmware and can be updated or replaced by the system administrator as needed.
