Lattice Codes for CRYSTALS-Kyber
Designs, Codes and Cryptography, 2023 This letter describes a lattice encoder for the NIST-recommended post-quantum encryption algorithm: Kyber. The key idea is to refine the analysis of Kyber decoding noise. We prove that Kyber decoding noise can be bounded by a sphere.
