5 Essential Best Practices for AI Data Security in the Post-Quantum Era

This blog post warns that adversaries are conducting "Harvest Now, Decrypt Later" (HNDL) attacks—collecting encrypted AI training data and model artifacts now to decrypt later with future quantum capabilities—and recommends five mitigation strategies: hybrid cryptography for transport, hardening the Model Context Protocol (MCP), embedding crypto‑agility, adopting quantum‑safe key management (HSMs), and continuous AI data posture monitoring to assess quantum risk.
