Quantum-Safe Signatures for AI Agents: Why ML-DSA Matters

Quantum computers will break RSA and ECDSA. If your AI agents sign actions today with classical cryptography, those signatures can be forged tomorrow. NIST finalized ML-DSA (FIPS 204) as the standard for post-quantum digital signatures. Why AI agents need quantum-safe signatures AI agents make consequential decisions. Audit trails signed with classical cryptography have a shelf life. Once quantum computers arrive, anyone can forge those records. Using ML-DSA with Asqav Asqav uses ML-DSA-44, ML-DSA-65, and ML-DSA-87 via liboqs. pip install asqav from asqav import Asqav client = Asqav ( api_key = " sk_... " ) agent = client . create_agent ( name = " financial-agent " , algorithm = " ML-DSA-65 " ) sig = client . sign ( agent_id = agent . agent_id , action_type = " transaction:approve " , action_id = " tx-001 " , payload = { " amount " : 50000 , " currency " : " EUR " } ) Algorithm comparison Algorithm Security Level Signature Size ML-DSA-44 2 2,420 bytes ML-DSA-65 3 3,309 bytes ML-DSA-87
