A memory protection key (MPK) [3] mechanism divides physical memory into blocks of a particular size (e.g., 4 KiB), each of which has an associated numerical value called a protection key. Each process also has a protection key value associated with it. On a memory access the hardware checks that the current process's protection key matches the ...
The two main use cases are Data at Rest protection, and Cryptographic Disk Erasure. For Data at Rest protection a computer or laptop is simply powered off. The disk now self-protects all the data on it. The data is safe because all of it, even the OS, is now encrypted, with a secure mode of AES, and locked from reading and writing. The drive ...

Typically, the keys would be of high value - meaning there would be a significant, negative impact to the owner of the key if it were compromised. The functions of an HSM are: onboard secure cryptographic key generation, onboard secure cryptographic key storage, at least for the top level and most sensitive keys, which are often called master keys,
