FINAL bootstrap acceleration on FPGA using DSP-free constant-multiplier NTTs

FINAL bootstrap acceleration on FPGA using DSP-free constant-multiplier NTTs

This work showcases Quatorze-bis, a state-of-the-art Number Theoretic Transform circuit for TFHE-like cryptosystems on FPGAs. It contains a novel modular multiplication design for modular multiplication with a constant for a constant modulus. This modular multiplication design does not require any...
