ML-DSA: Module Lattice Digital Signatures
The NIST-standardized post-quantum signature algorithm (formerly Dilithium).
🛡️ NIST Standardized (FIPS 204)
ML-DSA is the primary NIST post-quantum signature standard, published August 2024. It provides fast, compact quantum-resistant signatures suitable for high-volume applications.
📖 Definition
ML-DSA (Module Lattice-Based Digital Signature Algorithm) is the NIST-standardized name for Dilithium, a post-quantum digital signature scheme published as FIPS 204. It provides quantum-resistant signatures with performance comparable to classical algorithms, making it suitable for high-volume signing operations.
Technical Explanation
ML-DSA's security is based on the Module Learning With Errors (MLWE) problem—the same mathematical foundation as ML-KEM (Kyber). This provides algorithmic consistency across NIST's lattice-based standards.
Core Operations
- KeyGen(): Generates a public-private signing key pair
- Sign(sk, message): Creates a digital signature using the private key
- Verify(pk, message, signature): Verifies the signature is valid
Parameter Sets
| Parameter Set | NIST Security Level | Public Key Size | Signature Size |
|---|---|---|---|
| ML-DSA-44 | Level 2 (~128-bit) | 1,312 bytes | 2,420 bytes |
| ML-DSA-65 | Level 3 (~192-bit) | 1,952 bytes | 3,293 bytes |
| ML-DSA-87 | Level 5 (~256-bit) | 2,592 bytes | 4,595 bytes |
ML-DSA vs SPHINCS+
NIST standardized two post-quantum signature algorithms with different tradeoffs:
| Property | ML-DSA (Dilithium) | SLH-DSA (SPHINCS+) |
|---|---|---|
| Security Basis | Lattice (MLWE) | Hash functions only |
| Signature Size | 2-5 KB | 7-49 KB |
| Signing Speed | ~0.1 ms | ~10-100 ms |
| Verification Speed | ~0.1 ms | ~1-5 ms |
| Conservative Assumptions | Lattice hardness | Hash security only |
SynX Relevance
🔐 SynX Cryptographic Choice
While ML-DSA offers smaller signatures and faster performance, SynX chose SPHINCS+ (SLH-DSA) for transaction signatures due to its purely hash-based security:
- Assumption diversity: Different security basis from ML-KEM (Kyber)
- Maximum conservatism: Hash functions have decades of cryptanalysis
- Future-proof: If lattice problems were weakened, signatures remain secure
SynX's cryptographic agility architecture allows future ML-DSA adoption if desired.
When to Use ML-DSA
ML-DSA excels in applications where signature size and speed are critical:
- TLS/SSL certificates: Small signatures reduce handshake overhead
- High-frequency trading: Microsecond signing matters
- IoT/embedded devices: Limited storage and bandwidth
- Code signing: Compact signatures in software packages
