NTT Architecture for a Linux-Ready RISC-V Fully-Homomorphic Encryption Accelerator

IEEE Transactions on Circuits and Systems Part 1: Regular Papers, 2022
This paper proposes two architectures for the acceleration of Number Theoretic Transforms (NTTs) using a novel Montgomery-based butterfly. We first design a custom NTT hardware accelerator for Field-Programmable Gate Arrays (FPGAs).

HRCIM-NTT: An Efficient Compute-in-Memory NTT Accelerator With Hybrid-Redundant Numbers

IEEE Transactions on Circuits and Systems Part 1: Regular Papers
Recently, four NIST-approved Post-Quantum Cryptography (PQC) algorithms are selected to be standardized. Three of them are lattice-based cryptographic schemes and feature the number-theoretic transform (NTT) as the computing bottleneck compelling fast ...

3D-NTT: a versatile integral field spectro-imager for the NTT

SPIE Proceedings, 2008
The 3D-NTT is a visible integral field spectro-imager offering two modes. A low resolution mode (R ~ 300 to 6 000) with a large field of view Tunable Filter (17'x17') and a high resolution mode (R ~ 10 000 to 40 000) with a scanning Fabry-Perot (7'x7'). It will be operated as a visitor instrument on the NTT from 2009.
