Trojan-Resilient NTT: Protecting against Control Flow and Timing Faults on Reconfigurable Platforms

Number Theoretic Transform NTT is the most essential component for polynomial multiplications used in lattice-based Post-Quantum Cryptography PQC algorithms such as Kyber, Dilithium, NTRU etc. However, side-channel attacks SCA and hardware vulnerabilities in the form of hardware Trojans may alter...

GHSA-HVH4-5QR6-3V7R Observable Timing Discrepancy in pypqc

Impact kyber512, kyber768, and kyber1024 on Mac OS \or when compiled with clang\ only: An attacker able to submit many decapsulation requests against a single private key, and to gain timing information about the decapsulation, could recover the private key. Proof-of-concept exploit exists for a...
