Abstract
Embodiments include systems, methods, and apparatuses associated with storing data in a persistent memory are disclosed herein. In embodiments, a memory controller may be configured to encrypt data with an encryption key, and the encrypted data may be stored in persistent memory. The memory controller may be further configured to alter and/or destroy the encryption key in response to a reset event. Other embodiments may be disclosed and/or claimed.
Claims18
An apparatus comprising:
- a memory controller configured to alter or destroy, in response to a reset event, an encryption key employed to encrypt a data before storage of the data in a persistent memory, wherein the persistent memory is controlled by the memory controller.
A method comprising:
- encrypting, by a memory controller, a data based at least in part on an encryption key to create an encrypted data;
- storing, by the memory controller, the encrypted data in a nonvolatile memory;
- receiving, by the memory controller, an indication of a reset event;
- and
- destroying, by the memory controller, the encryption key in response to receiving the indication of the reset event.
2 more elements
A system comprising:
- a persistent memory configured to store an encrypted data;
- a memory controller coupled with the persistent memory and configured to:
- receive an indication of a reset event;
- and
- destroy, in response to the indication of the reset event, an encryption key employed to encrypt the encrypted data before storage of the encrypted data in the persistent memory.
