Rank Ceiling for Twiddle-Perturbation Faults on the Forward NTT
Formal analysis establishes an upper bound on the effectiveness of twiddle-perturbation fault attacks against NIST's ML-KEM/ML-DSA NTT implementations — informing post-quantum crypto hardening decisions.

arXiv:2610.30383v1 Announce Type: new Abstract: NIST standardised ML-KEM and ML-DSA in 2024 for post-quantum key establishment and digital signatures. Both compute forward number-theoretic transforms (NTTs) on secret polynomials. Published attacks zero every fixed multiplier, or twiddle, during Kyber key generation with a single fault, or individual twiddles in one Dilithium signing variant; countermeasures detect or mask these faults. Nonzero replacements preserve invertibility, but the uncomp
Editorial Analysis
As organisations prepare post-quantum migration roadmaps, understanding fault-injection attack limits on NIST-standardised algorithms helps prioritise hardware countermeasure investments.
Share findings with cryptographic library vendors to validate that their ML-KEM/ML-DSA implementations include adequate fault-injection countermeasures.
