Concurrent Error Detection in Montgomery Multiplication over Binary Extension Fields
Bibliographic record
Abstract
Multiplication is one of the most important operations in finite field arithmetic. It is used in cryptographic and coding applications, such as elliptic curve cryptography and Reed-Solomon codes. In this paper, we consider the finite field multiplication used in elliptic curve cryptography and design concurrent error detection circuits. It is shown in the literature that the Montgomery multiplication can be used in cryptography to accelerate the scalar multiplication. Here, we use a parity-based concurrent error detection approach to increase the reliability of different Montgomery multipliers available in the literature. First, we consider bit-serial Montgomery multiplication and propose an error detection circuit. Then, we apply the same technique on the digit-serial Montgomery multiplication. Finally, we consider low time-complexity bit-parallel Montgomery multiplication and design the required components to implement the concurrent error detection circuits. ASIC implementations have been completed to analyze the time and area overheads of the proposed schemes. Also, the error detection capability is investigated by software simulations. We show that our approach results in efficient error detection schemes with small time and area overheads.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
