Conceptually, the Pluton architecture is an extension of hardware security work that Microsoft started in 2013 with onboard anti-piracy protections for the Xbox One console, though in case that sounds dangerously consumerish the firm is also keen to say the same approach was ported across to Arm-based system-on-chip IoT thingy Azure Sphere too.
Future CPU designs from AMD, Intel, and Qualcomm will incorporate Pluton technology, with all three chipmakers queuing up to dutifully say what a great idea this is: "We believe an on-die, hardware-based Root-of-Trust like the Microsoft Pluton is an important component in securing multiple use cases and the devices enabling them," stated Asaf Shen, Qualcomm's senior director of product management in a prepared remark.
Microsoft hopes to remove that distinction by adding the root-of-trust component directly into the silicon.
"Windows PCs using the Pluton architecture will first emulate a TPM that works with the existing TPM specifications and APIs which will allow customers to immediately benefit from enhanced security for Windows features that rely on TPMs like BitLocker and System Guard," said Microsoft.
In its post Microsoft claimed: "Windows devices with Pluton will use the Pluton security processor to protect credentials, user identities, encryption keys, and personal data. None of this information can be removed from Pluton even if an attacker has installed malware or has complete physical possession of the PC.".
