Abstract
Methods, apparatuses, and systems related to securing memory data are described. A hardware circuit is configured to encrypt and decrypt memory data using a scrambling key unique to a computing process processing the memory data. In writing the memory data, the hardware circuit generates scrambled memory data based on encrypting the memory data according to the security key. The scrambled memory data is stored for the write operation instead of the memory data. When the same process reads back the scrambled data, the same security key can be used to decrypt the scrambled data and recover the initial unscrambled memory data.
