Abstract
In this paper the authors present a new compact iterative architecture of 32-bit datapath for the AES block cipher. The authors propose a new way of implementing ShiftRows and InvShiftRows operation, which is realized by the simple enable function of registers and five 2-to-1 multiplexors of eight bits length. A new compact key generation unit of 32-bit datapath is also proposed to generate round keys on-the-fly for both encryption and decryption. The hardware resource is maximally shared for encryption and decryption. The implementation requires 9843 gate equivalents and provides a throughput of 247 Mbit/s on the CSMC's 0.35 <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">μ</i> m CMOS technology. The comparison with the best previous work shows that it has better throughput and area performance parameters.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
