Abstract:This work explores several architectural optimizations to report a fast and area-time (AT) product efficient hardware accelerator for a lattice based Key Encapsulation Mechanism (KEM) scheme called the CRYSTALS-KYBER. Kyber was recently chosen as the first quantum resistant KEM scheme for standardisation, after three rounds of the National Institute of Standards and Technology (NIST) initiated NIST PQC competition for the search of the best quantum resistant KEMs and digital signatures (started in 2016). Kyber is based on Module-Learning with Errors (M-LWE) class of Lattice-based Cryptography, that is known to manifest efficiently on FPGAs. The architectural optimizations include inter-module and intra-module pipelining, that is designed and balanced via FIFO based buffering to ensure maximum parallelisation. The implementation results show that compared to the state-of-the-art, the proposed architecture delivers 23.8-43.8% speedups at three different security levels on Artix-7 and Zynq UltraScale+ devices, 50-75% reduction in DSPs and no BRAM resources at comparable security level. Consequently, the AT product efficiency is reported to be 45.8-51.9% higher in comparison with the state-of-the-art designs.
