AIMer Security API

Version: 1.0.0
Last Updated: 2025-01-02
Security Classification: MPC-based Signature
Author: MetaMUI Security Team

Overview

AIMer is a Korean signature scheme based on MPC-in-the-head paradigm, offering quantum resistance through symmetric primitives.

• Algorithm Family: MPC-in-the-head signature
• Security Levels:
  • 128f: 128-bit (fast variant)
  • 192f: 192-bit (fast variant)
  • 256f: 256-bit (fast variant)
• Origin: Korean Post-Quantum Cryptography Competition

Security Warnings ⚠️

1. MPC-based: Uses multiparty computation techniques
2. Symmetric Primitives: Security based on AES
3. Large Signatures: Larger than lattice-based schemes
4. Simple Implementation: Easier to implement securely

API Functions

Standard signature API with MPC-based construction.
