Optimized Design and Implementation of CRYSTALS‐KYBER Based on MLWE

Security and Communication Networks, Volume 2025, Issue 1, 2025.
CRYSTALS‐KYBER is a postquantum key exchange mechanism based on the MLWE problem. At present, it is a major challenge to realize CRYSTALS‐KYBER with high‐performance and low‐resource consumption on the FPGA platform. The design proposed in this paper aims at the high efficiency implementation of CRYSTALS‐KYBER based on the MLWE scheme.
