AMD Platform Security Processor settings in an UEFI configuration screen. The AMD Platform Security Processor (PSP), officially known as AMD Secure Technology, is a trusted execution environment subsystem incorporated since about 2013 into AMD microprocessors. [1]
The Open Mobile Terminal Platform (OMTP) first defined TEE in their "Advanced Trusted Environment:OMTP TR1" standard, defining it as a "set of hardware and software components providing facilities necessary to support applications," which had to meet the requirements of one of two defined security levels. The first security level, Profile 1 ...
This is the first stage of the UEFI boot but may have platform specific binary code that precedes it. (e.g., Intel ME, AMD PSP, CPU microcode). It consists of minimal code written in assembly language for the specific architecture. It initializes a temporary memory (often CPU cache-as-RAM (CAR), or SoC on-chip SRAM) and serves as the system's ...
Updates add new functionality as well as security patches to prevent unsigned code from being executed on the system. Updates can be obtained in four ways: Direct download to the PSP over Wi-Fi. This can be performed by choosing [Settings], [System Update] from the XMB. Download to a PC, then transfer to the PSP via a USB cable or Memory Stick.
The Electronic Frontier Foundation and some security researchers have voiced concern that the Management Engine is a backdoor. Intel's main competitor, AMD, has incorporated the equivalent AMD Secure Technology (formally called Platform Security Processor) in virtually all of its post-2013 CPUs.
AMD Generic Encapsulated Software Architecture (AGESA) is a procedure library developed by Advanced Micro Devices (AMD), used to perform the Platform Initialization (PI) on mainboards using their AMD64 architecture.
