Intel Total Memory Encryption – Multi-Key (TME-MK) enhances runtime data protection by enabling page-level memory encryption using multiple keys. Built into 12th Gen Intel vPro processors, TME-MK encrypts memory during use, helping defend against physical and cold boot attacks. It allows OS or hypervisors to assign encryption keys per memory page, supporting isolated VMs and shared memory use cases. TME-MK mitigates advanced threats like data leaks and replay attacks using AES-XTS encryption. Integrated with Windows 11 22H2 and Hyper-V, it supports secure hybrid environments without compromising performance.
