Haetae Security API

Version: 1.0.0
Last Updated: 2025-01-02
Security Classification: Korean PQC Signature
Author: MetaMUI Security Team

Overview

Haetae is a Korean lattice-based digital signature scheme with compact signatures and efficient verification.

• Algorithm Family: Lattice-based signature
• Security Levels:
  • Level 2: 128-bit
  • Level 3: 192-bit
  • Level 5: 256-bit
• Origin: Korean Post-Quantum Cryptography Competition

Security Warnings ⚠️

1. Compact Signatures: Smaller than ML-DSA
2. Efficiency: Optimized for verification speed
3. Korean Standard: Regional standardization
4. Lattice-based: Based on module-SIS problem

API Functions

Similar structure to ML-DSA with Korean-specific optimizations.
