Microsoft Pluton processor

Today, Microsoft is working with major chipmaker partners to unveil a new vision for Windows security.

Microsoft Pluton Security Processor has been implemented in collaboration with - AMD, Intel and Qualcomm Technologies, Inc.

Pluton's design eliminates the possibility of attack by providing security directly to the CPU. Windows devices running Pluton will use the Pluton security processor to protect credentials, user IDs, encryption keys, and personal information. None of this information can be removed from Pluton, even if an attacker installs malware or takes full physical control of the computer.

It does this by safely storing sensitive data, such as encryption keys, in the Pluton processor, which is isolated from the rest of the system, which helps prevent access to keys through new attack methods such as speculative execution.
Pluton also provides the unique Secure Hardware Cryptography Key (SHACK) technology.

Windows computers using the Pluton architecture will first emulate a TPM that will work with existing TPM specifications and APIs, allowing consumers to immediately take advantage of the enhanced security benefits of Windows TPM-based features such as BitLocker and System Guard.
