Abstract
Differential power analysis is an effective way to crack the key of the cryptographic chip. The attacker can analyze the key by monitoring the power curve during the execution of their internal programs, which poses a serious threat to the security of the cryptographic device. In order to improve the capability of anti-power analysis of the cryptographic chip, a novel configurable current flattening circuit (CCFC) based on power balance principle is proposed. The circuit is independent of the cryptographic algorithm and does not affect the original design flow of the cryptographic chip. In this paper, the circuit is designed under the SMIC 65nm CMOS technology. The test results show that the circuit can work effectively over a wide frequency range, the flattened current value can be adjusted from 0 to 32mA, and the attenuation of current variations on the power supply can reach 96.2%.

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
