Post-Quantum Cryptography: The Enterprise Security Mandate for 2030
In August 2024, NIST finalized three post-quantum cryptography standards: FIPS 203 (ML-KEM), FIPS 204 (ML-DSA), and FIPS 205 (SLH-DSA). IBM's roadmap targets its first fault-tolerant quantum system ('Starling') by 2029. Expert consensus places Q-Day — the cryptographically relevant quantum computer — in the early-to-mid 2030s. The 'Harvest Now, Decrypt Later' attack vector is active today. This dossier maps the enterprise migration mandate, the technical standards, and the intelligence required to navigate the transition.
