Abstract
In this paper, we present a comprehensive investigation of the influence of pipeline configurations on the performance of ASIC implementations of the Advanced Encryption Standard (AES) substitution box (S-box) based on a composite field structure. We consider pipeline configurations for the S-box with a typical composite field structure by varying the number of pipeline stages and the placement approach of pipeline registers. Besides the conventional placement approach at the component level of the S-box, we adopt a new placement approach at the gate level to achieve a fine-grained pipeline. The performance of the pipelined S-boxes is characterized based on a 90-nm standard cell CMOS technology. The characterization shows that there is notable performance improvement in timing, area, power and/or energy efficiency by using an appropriate configuration compared with other configurations including non-pipelined implementations. These results are strong evidence that pipelined S-box implementations are not only suitable for high throughput AES implementations, but also valuable to resource-efficient AES implementations. In addition, it is also shown that pipelining provides many more performance options that allow more flexible implementation of the AES S-box compared with non-pipelined implementations.

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
