Özet

Since the debut of the Advanced Encryption Standard (AES), it has been thoroughly studied by hardware designers with the goal of reducing the area and delay of the hardware implementation of this cryptosystem. This paper proposes an implementation of the AES Mix Columns operation. In this paper, a compact architecture for the AES mix columns operation and its inverse is presented. The hardware implementation is compared with previous work done in this area. We show that our design has a lower gate count than other designs that implement both the forward and the inverse mix columns operation.
