Falcon-1024 Security API

Version: 1.0.0
Last Updated: 2025-01-02
Security Classification: Lattice-Based Signature
Author: MetaMUI Security Team

Overview

Falcon-1024 is a Fast Fourier lattice-based signature scheme providing NIST security level 5 with compact signatures.

• Algorithm Family: NTRU lattice-based signature
• NIST Security Level: Level 5 (256-bit security)
• Key Sizes:
  • Public Key: 1793 bytes
  • Secret Key: 2305 bytes
  • Signature: ~1280 bytes (variable)
• NIST Round: Round 4 candidate

Security Warnings ⚠️

1. Floating-Point Free: Implementation avoids floating-point for security
2. Variable Signature Size: Signatures have variable length
3. Complex Implementation: Requires careful implementation
4. Maximum Security: Level 5 post-quantum security

API Functions

Similar to Falcon-512 with level 5 security parameters.
