Storing and providing access to Advanced Encryption Standard round keys using dual-port storage devices

Abstract

A system includes one or more processing units configured to generate a first set of round keys for rounds of an Advanced Encryption Standard (AES) algorithm using a first encryption key; to generate a second set of round keys using a second encryption key; to determine different addresses of a plurality of storage devices for the first and second sets of round keys; and to store the first and second sets of round keys at the different addresses, wherein the first round key is stored in one storage device of the plurality of storage devices using a first port of the storage device, and wherein the storage device is a dual-port storage device comprising the first port and a second port.
