Abstract: In some examples, securing data on a computing device includes one or more cryptographic operations on at least a portion of data stored in a memory module of the computing device in response to a change of operational state of the system from a first operational state to a second operational state.

Abstract: A computing device that includes a non-volatile memory device comprising an ephemeral memory region therein, the ephemeral memory region being encrypted and comprising an associated encryption key; and firmware to cause the encryption key to be stored prior to any power loss to the computing device.

Abstract: A system includes a server and a computer. The server stores a non-volatile dual in-line memory module (NVDIMM) configuration profile. The computer includes a plurality of NVDIMMs. The computer downloads the NVDIMM configuration profile from the server and applies the NVDIMM configuration profile to the plurality of NVDIMMs.

Abstract: Examples of a system and method for securing data on a computing device are described herein. One or more cryptographic operations are executed on at least a portion of data stored in a memory module of the computing device in response to a change of operational state of the system from a first operational state to a second operational state.

Abstract: Examples associated with persistent memory updating are described. One example includes receiving a first store instruction associated with a first page of memory in a persistent memory from an application. The first page is copied to a new page of the persistent memory. A virtual address space of the application is updated to a location of the new page in a read-write mode. The first store instruction is executed on the new page. A file mapping in the persistent memory is updated from a location of the first page to the location of the new page, and the virtual address space for the location of the new page is updated to a read-only mode.

Abstract: One example of a system includes a plurality of machine-readable storage devices, a machine-readable storage medium, and platform firmware. Each machine-readable storage device is to be unlocked for read and/or write access via a passphrase for each machine-readable storage device. The machine-readable storage medium stores an encrypted passphrase for each machine-readable storage device. The platform firmware is to receive a user token, derive a key from the user token, decrypt the encrypted passphrase stored in the machine-readable storage medium for each machine-readable storage device using the key, and unlock each machine-readable storage device using the decrypted passphrase for each machine-readable storage device.

Abstract: Examples of a system and method for securing data on a computing device are described herein. One or more cryptographic operations are executed on at least a portion of data stored in a memory module of the computing device in response to a change of operational state of the system from a first operational state to a second operational state.

Abstract: Examples include a system comprising a processing resource and a memory resource. Examples include a cryptography engine arranged in-line with the processing resource and the memory resource. The cryptography engine is to selectively decrypt data during read accesses of the memory resource by the processing resource.
