This paper proposes using a generalized minimum-distance (GMD) soft-decision Reed-Solomon decoder for HQC post-quantum cryptography, significantly reducing required codeword length and improving hardware efficiency.

The paper proposes a novel triple-hoisted baby-step giant-step algorithm and a memory-optimized FPGA accelerator to significantly reduce the ciphertext rotations and off-chip memory access latency when performing linear transformations over CKKS homomorphic encryption.
