ML-DSA-65 Security API

Version: 1.0.0
Last Updated: 2025-01-02
Security Classification: Digital Signature Algorithm
Author: MetaMUI Security Team

Overview

ML-DSA-65 (formerly Dilithium3) provides NIST security level 3, offering balanced security and performance for digital signatures.

• Algorithm Family: Lattice-based signature
• NIST Security Level: Level 3 (≥192-bit classical security)
• Key Sizes:
  • Public Key: 1952 bytes
  • Secret Key: 4000 bytes
  • Signature: 3293 bytes
• Standard: FIPS 204

Security Warnings ⚠️

1. Medium-High Security: Suitable for most applications requiring long-term security
2. Performance Balance: Good trade-off between security and speed
3. Memory Usage: Moderate memory requirements
4. Quantum Resistance: Strong post-quantum security

API Functions

Similar to ML-DSA-44 with adjusted parameters for level 3 security.
