Distill-and-Rank: Evaluating Fast Transformer Models for Keyless PQC Side-Channel Recovery
Post-quantum cryptography (PQC) schemes such as the NIST-standardized ML-KEM (CRYSTALS-Kyber) are entering deployment, yet their resilience to side-channel attacks (SCAs) remains insufficiently understood. We study a realistic keyless attack on ML-KEM’s pointwise multiplication: a leakage model trained only on a disjoi...
