The Number Theoretic Transform (NTT) is a critical subblock used in several structured lattice-based schemes, including Kyber and Dilithium, which are finalist candidates in the NIST’s standardization process for post-quantum cryptography. The NTT was shown to be susceptible to single trace side-c...
