PIP-NTT: Towards a Scalable Memory-Parallelized Accelerator for Iterative NTT in PQC

The iterative forward and inverse number theoretic transform (NTT) is a key component in lattice-based post-quantum cryptography (PQC), typically implemented using Cooley-Tukey and Gentleman-Sande butterfly units. Existing iterative NTT accelerators often rely on ping-pong memory schemes and large memory blocks tied to...
