Sanjay Deshpande, Mamuri Nawan, Kashif Nawaz, Jakub Szefer, Chuanqi Xu

This work presents a hardware design for constant-time implementation of the HQC (Hamming Quasi-Cyclic) code-based key encapsulation mechanism. HQC has been selected for the fourth-round of NIST's Post-Quantum Cryptography standardization process and this work presents first, hand-optimized design of HQC key generation, encapsulation, and decapsulation written in Verilog targeting implementation on FPGAs. The three modules further share a common …
