Abstract
This document discloses data security systems and methods of securing data. A cache memory can be connected between a decryption engine and a central processing unit ('CPU') to increase security of encrypted data that is stored in a datastore. The decryption engine can retrieve the encrypted data from the datastore, decrypt the data, and store the decrypted data in the cache. In turn, the decrypted data can be accessed by the CPU. The data can be encrypted with a secret key, so that decryption can be performed with the secret key. The key can be varied based on a memory address associated with the data. The key can be protected by restricting direct access to the decryption engine by the CPU.
