High-Speed NTT Accelerator for CRYSTAL-Kyber and CRYSTAL-Dilithium

IEEE Access
The efficiency of polynomial multiplication execution majorly impacts the performance of lattice-based post-quantum cryptosystems. In this research, we propose a high-speed hardware architecture to accelerate polynomial multiplication based on the Number Theoretic Transform (NTT) in CRYSTAL-Kyber and CRYSTAL-Dilithium.
