Abstract
Lattice-based cryptography (LBC) is one of the most promising classes of post-quantum cryptography (PQC) that is being considered for standardization. This brief proposes an optimized schoolbook polynomial multiplication (SPM) for compact LBC. We exploit the symmetric nature of Gaussian noise for bit reduction. Additionally, a single field-programmable gate array (FPGA) DSP block is used for two parallel multiplication operations per clock cycle. These optimizations enable a significant 2.2× speedup along with reduced resources for dimension n = 256. The overall efficiency (throughput per slice) is 1.28× higher than the conventional SPM, as well as contributing to a more compact LBC system compared to previously reported designs. The results targeting the FPGA platform show that the proposed design can achieve high hardware efficiency with reduced hardware area costs.

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
