The work builds upon the study [1] by Roche, Imbert, and Lomné. The objective is to reproduce and extend the results of the original paper, which analyzes side-channel attacks on blinded scalar multiplications used in elliptic-curve cryptography. The student will first implement and verify the published attack, confirming its correctness and success rates under various parameters such as noise level, bit error rate, and the number of observed traces. After validating the baseline, the student will analyze the attack’s behavior, identify its limitations, and propose modifications that improve the success rate or minimize the number of signatures. The results should be experimentally verified and discussed in terms of accuracy, performance, and robustness.
