ML-KEM vs ML-DSA vs SLH-DSA: Which Is Best for Post-Quantum Signatures?
RSA and ECC are geared toward the day quantum computers arrive, and the industry is trying to get ahead of the curve. NIST has adopted three algorithms for key establishment (ML-KEM), ML-DSA, and SLH-DSA for signatures. NIST has recently completed three post-quantum standards that will help keep systems secure when quantum computers can break RSA/ECS encryption. ML-KEM is used for setting up shared secrets via key encapsulation and is not a signature algorithm.
