Adversaries are already running Harvest-Now-Decrypt-Later (HNDL) campaigns against AI infrastructure, collecting encrypted model weights and training data to decrypt once quantum computers arrive. The post outlines 7 quantum-resistant methods for securing AI pipelines: hybrid key exchange combining classical ECDH with ML-KEM, quantum-safe TLS 1.3, PQC for Model Context Protocol connections, lattice-based ML-DSA signatures for model provenance, SLH-DSA hash-based signatures for firmware integrity, policy-driven crypto-agility, and post-quantum secret management. It covers the NIST FIPS 203/204/205 standards and provides a 4-phase migration checklist covering discovery, pilot testing, threat monitoring, and continuous automation.
