Post-Quantum

Definitions

1. Describing cryptographic algorithms, migration efforts, or threat models designed to remain secure against attackers with large-scale quantum computers. Post-quantum security work focuses on replacing or augmenting public-key systems vulnerable to quantum attacks while maintaining practical deployment properties.

   In plain English: Designed to stay secure even if powerful quantum computers can break some current cryptography.

   Example: "The PKI roadmap added post-quantum planning because long-lived secrets encrypted today could still matter when stronger quantum-capable adversaries arrive."
