Fiddling the Twiddle Constants - Fault Injection Analysis of the Number Theoretic Transform

2023 · IACR Transactions on Cryptographic Hardware and Embedded Systems

In this work, we present the first fault injection analysis of the Number Theoretic Transform (NTT). The NTT is an integral computation unit, widely used for polynomial multiplication in several structured lattice-based key encapsulation mechanisms …
