NTT-PEEL: Bit Shift Side-Channel in FALCON’s Number Theoretic Transform
IACR Transactions on Cryptographic Hardware and Embedded SystemsThis work introduces a new single-trace side-channel attack against FALCON, a lattice-based post-quantum digital signature scheme recently selected for standardization by NIST. The proposed attacks exploit a new vulnerability in the in-place modular reduction within the number theoretic transform (NTT). The vulnerable component executes both in the key
