Applying the Simple Partial Discard Method to Crystals-Kyber [PDF]
IEEE AccessIn certain cryptographic applications random numbers are required (e.g., when generating cryptographic keys and generating digital signatures). To obtain these random numbers, the typical approach involves obtaining random bits first and then converting ...

Lattice Codes for CRYSTALS-Kyber [PDF]
Designs, Codes and Cryptography, 2023 <p>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. This result shows the Kyber encoding problem is essentially a sphere packing in a hypercube.

CRYSTALS-Kyber With Lattice Quantizer [PDF]
2024 IEEE International Symposium on Information Theory (ISIT)Module Learning with Errors (M-LWE) based key reconciliation mechanisms (KRM) can be viewed as quantizing an M-LWE sample according to a lattice codebook. This paper describes a generic M-LWE-based KRM framework, valid for any dimensional lattices and any modulus $q$ without a dither. Our main result is an explicit upper bound on the decryption failure
