Abstract
Because of their shorter key sizes, cryptosystems based on elliptic curves are being increasingly used in practical applications. A special class of elliptic curves, namely, Koblitz curves, offers an additional, but crucial advantage of considerably reduced processing time. Power analysis attacks are applied to cryptosystems that use scalar multiplication on Koblitz curves. Both the simple and the differential power analysis attacks are considered and a number of countermeasures are suggested. While the proposed countermeasures against the simple power analysis attacks rely on making the power consumption for the elliptic curve scalar multiplication independent of the secret key, those for the differential power analysis attacks depend on randomizing the secret key prior to each execution of the scalar multiplication. These countermeasures are computationally efficient and suitable for hardware implementation.

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
