CRYSTALS Kyber core for accelerating NIST FIPS 203 Key Encapsulation Mechanism

Overview

eSi-Kyber is a hardware accelerator core designed to accelerate post-quantum Key Encapsulation Mechanism (KEM) as defined by NIST FIPS 203.

Kyber, an integral part of the Cryptographic Suite for Algebraic Lattices (CRYSTALS), is an IND-CCA2-secure key encapsulation mechanism known as ML-KEM. Its security is derived from the complexity of solving the learning-with-errors (LWE) problem over module lattices.

CRYSTALS encompasses two cryptographic primitives: Kyber, a secure KEM, and Dilithium, a strongly EUF-CMA-secure digital signature algorithm.

Key Features

The core supports all operations defined in the FIPS 203 standard :
- ML-KEM.KeyGen
