Which boot process enhances security but does not require a Trusted Platform Module for operation?

The concept of Secure Boot is fundamentally designed to ensure that a device boots using only software that is trusted by the Original Equipment Manufacturer (OEM). During the boot process, Secure Boot verifies the digital signatures of each piece of boot software before allowing it to execute. This helps prevent unauthorized code from running on the system, effectively enhancing the security of the boot process by ensuring that the operating system and other software components have not been tampered with.

Notably, Secure Boot does not require a Trusted Platform Module (TPM) to function. While a TPM can provide additional features such as storing cryptographic keys securely or enhancing platform integrity measurement, Secure Boot can operate independently of it. This distinguishes Secure Boot from other mechanisms that may rely on TPM to provide a secure environment for booting.

In contrast, other choices like Measured Boot involve verification processes that do typically rely on TPM for storing the measurement logs, thereby tightly integrating with the hardware. UEFI is a modern firmware interface that supports Secure Boot but is not itself a security feature; it's more about providing a standard environment for booting. The Trusted Platform Module is a hardware component whose primary role is to provide secure cryptographic functions but does not directly enhance the boot process without being part of another solution.
