Post-quantum security: harvest-now-decrypt-later explained
Harvest-now-decrypt-later (HNDL) is the practice of copying encrypted traffic and stored ciphertext today, then decrypting it once a sufficiently capable quantum computer exists. For data with a long confidentiality window — bank records held 10–15 years, health records held 25+ years, defence material held longer still — that future event is already inside the protection window.
A credible response is staged: cryptographic inventory across applications, certificates, HSMs, VPNs and tunnels; an HNDL risk model that weights assets by remaining confidentiality life; HSM/KMS upgrades to algorithms standardised by NIST (FIPS 203 ML-KEM, FIPS 204 ML-DSA, FIPS 205 SLH-DSA); a hybrid TLS phase where classical and post-quantum handshakes run side-by-side; then full rollout with continuous supply-chain crypto assurance.
How JAQL applies this: the HIQTF framework (SSRN preprint 6581378) describes a zero-trusted-node transmission architecture, and the JAQL PQC engagement runs the five-phase rollout in 90–180 days inside the client's own systems. See /post-quantum-security and /frameworks/hiqtf/.
