Harvest-now threat model
Adversary records ciphertext or public transcripts today for future cryptanalysis—core HNDL framing.
Definition
Under harvest-now models, defenders assume sophisticated adversaries store TLS, VPN, or archive ciphertext. Future CRQC or cryptanalysis may unlock it.
Mitigations emphasize hybrid key exchange now and re-encryption of long-lived stores—see HNDL.
