Microsoft Pluton security processor is a chip-to-cloud security technology built with Zero Trust principles at the core. Microsoft Pluton provides hardware-based root of trust, secure identity, secure attestation, and cryptographic services. Pluton technology is a combination of a secure subsystem which is part of the System on Chip (SoC) and Microsoft authored software that runs on this integrated secure subsystem.
Microsoft Pluton is currently available on devices with Ryzen 6000 and Qualcomm Snapdragon® 8cx Gen 3 series processors. Microsoft Pluton can be enabled on devices with Pluton capable processors running Windows 11, version 22H2.
What is Microsoft Pluton?
Designed by Microsoft and built by silicon partners, Microsoft Pluton is a secure crypto-processor built into the CPU for security at the core to ensure code integrity and the latest protection with updates delivered by Microsoft through Windows Update. Pluton protects credentials, identities, personal data and encryption keys. Information is significantly harder to be removed even if an attacker has installed malware or has complete physical possession of the PC.
Microsoft Pluton is designed to provide the functionality of the Trusted Platform Module as well as deliver other security functionality beyond what is possible with the TPM 2.0 specification, and allows for additional Pluton firmware and OS features to be delivered over time via Windows Update. For more information, see Microsoft Pluton as TPM.
It sounds like this will become a problem if/when content providers start requiring it.
Like how Netflix requires certain hardware to enable 4K. (At least I think they do? I remember that was a thing a few years ago.)
