Overview
Explore a conference talk on rotational symmetry for FPGA-specific AES implementation. Delve into the paper presented by Lauren De Meyer, Amir Moradi, and Felix Wegener at CHES 2018, which introduces innovative approaches to AES Sbox design. Learn about Boolean functions in ASIC, slices, and various AES Sbox implementation techniques. Discover the authors' contributions, including rotational symmetry theory, new heuristics, and circuit designs. Examine state operations, mix columns, and sidechannel protection measures. Evaluate the full Sbox implementation and gain insights into power functions. Conclude with a summary and Q&A session, enhancing your understanding of advanced cryptographic hardware design.
