- Total Memory Encryption - Multi Key. This is AMD SEV's Intel counterpart - it provides memory encryption to protect the host from cold boot attacks and make VM break outs harder. This is a mandatory requirement to meet HSI level 4 on Linux.
- Intel Key Locker - This feature makes it possible to encrypt and decrypt data with an AES key using a key handle instead of the actual encryption key. A key handle can be revoked when the system state changes, such as with a reboot. This feature is not widely used on Linux, although it is already available on Chromebooks with vPro Enterprise.
- Intel Trusted Execution Technology (TXT). This feature implements Dynamic Root of Trust Measurement (DRTM) and is necessary for [System Guard](https://learn.microsoft.com/en-us/windows/security/hardware-security/how-hardware-based-root-of-trust-helps-protect-windows) on Windows. It is a pre-requisite for the Secure-cored certification. On Linux, DRTM is not widely used, but Trenchboot is being developed to address that.
