Nanoscale CMOS battery cells for gate level on‐chip security designs
Bibliographic record
Abstract
An efficient power analysis attack countermeasure at the transistor gate level using novel nanoscale CMOS battery cells in a decoupling‐based technique is presented. The proposed CMOS battery cells are used as decoupling elements between the gates implementing a sensitive operation inside a cryptographic module and the power supply rail of the integrated circuit. As a result, the battery cells form an intermediate on‐chip power storage element, providing a masked power supply point for gates that are on a critical security path. The circuitry of the battery cells and the gates are designed using 65 nm TSMC CMOS technology. A test system was simulated with an 8 bit XOR serving as a target operation for a correlation power analysis attack. A total of 16 battery cells, two per gate for complementary cycles, were created with 1.74 µm 2 P‐type MOS transistors serving as energy storage devices. Results showed that the test system offered protection at 10 000 traces.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
