§Dilithium Signature

This module implements the Dilithium digital signature algorithm using liboqs. Dilithium is EUF-CMA secure and is based on the hardness of the Module-LWE (Learning With Errors over Modules) problem.

§Security Level

  • Dilithium2: NIST Level 2 ≈ AES-128
  • Dilithium3: NIST Level 3 ≈ AES-192
  • Dilithium5: NIST Level 5 ≈ AES-256

§Usage

use ri::protocol::dilithium::DilithiumSigner;

let signer = DilithiumSigner::new();
let (public_key, secret_key) = signer.keygen()?;
let message = b"Hello, Post-Quantum World!";
let signature = signer.sign(&secret_key, message)?;
assert!(signer.verify(&public_key, message, &signature)?);
