Abstract: An Advanced Encryption Standard (AES) device and a computer-implemented method of performing an AES operation may be provided, the AES device comprising a state array of components comprising a first plurality of controllable data processing components, the first plurality of controllable data processing components including two or more controllable data processing state members that each include an additional input control and an additional input port; a key array of components comprising a second plurality of controllable data processing components; a control block module coupled to the state array of components and the key array of components, the control block module arranged to transmit one or more control signals to the state array of components and the key array of components; wherein the two or more controllable data processing state members are disposed at predetermined positions within the state array of components; and further wherein the control block module is arranged to instruct performance of one or more AES operations via usage of the additional input port of at least one of the two or more controllable data processing state members based on a clock cycle count.
