Payment card Industry: Secure Boot == Verified Boot == “Trusted Boot”

I just noticed that the PCI compliance group lumps all of the Trusted/Measured/Verified/Secure boot technologies into one, and calls it Trusted Boot, which, AFAIK, is the name for Intel TXT-based Trusted Boot. I wish they were more precise. Then again, I guess I should be glad there is *SOME* firmware security in the PCI compliance docs, I wish there was more, system should check firmware-based code for malware, not just OS-based code.

Payment Card Industry (PCI)
Software-based PIN Entry on COTS Security Requirements
Version 1.0, January 2018
The PIN CVM Application must only support platforms that, at a minimum, provide the following features:

* An enforcing mandatory access control framework
* A “trusted boot” mechanism that validates the operating system’s authenticity

Trusted Boot: A cryptographic process where the bootloader verifies the integrity of all components (e.g., kernel objects) loaded during operating system start-up process, before loading. Also known as Verified Boot and Secure Boot (e.g., Google or Apple).
