Abstract
A control unit includes at least one electrically erasable programmable read-only memory (EEPROM) configured to store data. The control unit also includes a standby random access memory (RAM) configured to store encrypted data that encrypts a value corresponding to the data with a roll-back key. The control unit additionally includes a control circuit configured to decrypt the encrypted data with the roll-back key to generate decrypted data and roll back the data using the decrypted data.
