Some more details from Tom's Hardware Guide: https://www.tomshardware.com/news/microsoft-pluton-processor-intel-adopt-amd-security-approach https://www.tomshardware.com/news/microsoft-pluton-processor... In particular, Microsoft says that the the idea of Pluton was pioneered in the AMD-Microsoft co-designed chip for the Xbox One. Tom's Hardware also compares it to the AMD Platform Security Processor (https://en.wikipedia.org/wiki/AMD_Platform_Security_Processor https://en.wikipedia.org/wiki/AMD_Platform_Security_Processo... ), which is AMD's CPU-embedded answer to Intel's chipset-embedded Management Engine. Both PSP and ME have had several reported security vulnerabilities. I wouldn't be surprised if on AMD CPUs, Pluton is implemented as basically just reflashing PSP's firmware. As Microsoft is much more experienced at secure software than the AMDs and Intels of the world, I have a bit more hope about Pluton not introducing an accidental back door into my machine!
