3.2.2 On-the-fly-Security Engine

OptiFlash provides a security engine with in-line encryption/decryption/authentication (AES/GCM) on flash data to enable secure external flash use. It supports on-the-fly address translation to provide SW transparent view to account for additional storage of Message Authentication Code (MAC). MAC size is programmable
