PCs Take a Page From Xbox With Pluton.

Microsoft's Pluton is dedicated silicon that aims to strengthen the security and integrity of PCs; it is derived from the Xbox One video game console SoC which was designed in partnership between Microsoft and AMD. Pluton implements and extends the functionality of the Trusted Computing Group's (TCG) Trusted Platform Module 2.0, protects keys as they move around the SoC using dedicated silicon referred to as Secure Hardware Cryptography Key, and implements the TCG's Device Identifier Composition Engine and Microsoft's Robust Internet of Things specifications to perform strong device attestation with a hardware root of trust. While Microsoft is following Apple and Google's lead by integrating special-purpose silicon for secure cryptographic operations, it is taking a different approach by leveraging existing open standards and technologies. Microsoft's Windows 11 is designed for a world where all PCs feature Pluton. [ABSTRACT FROM AUTHOR]
