contributes to the area, delay, and power of AES accelerators. Unlike typical logic gate S-
Box implementations, we use full-custom 256× 8-bit ROMs, which significantly improve
performance and efficiency. We implemented a fully-unrolled, pipelined AES-128 encryption
accelerator using ROM-based S-Boxes in 65nm bulk CMOS which operates at 2.2 GHz and
consumes 523mW at 1.0 V, 27° C. In counter-mode operation (CTR), the throughput is 275.2 …
