Post-quantum cryptography: getting ready for Q-day

Why this is not science fiction

Most of today's secure communication relies on RSA and elliptic-curve cryptography. A sufficiently powerful quantum computer running Shor's algorithm would break both. We do not know exactly when "Q-day" arrives — but we know adversaries are already harvesting encrypted data now to decrypt it later.

What post-quantum cryptography is

Post-quantum cryptography (PQC) is a family of algorithms designed to resist both classical and quantum attacks. In 2024 NIST standardized the first ones (such as ML-KEM and ML-DSA), and migration has started across the industry.

What organizations should do

• Inventory where you use vulnerable cryptography (TLS, VPNs, signing, stored secrets).
• Prioritize long-lived secrets — data that must stay confidential for a decade is at risk today.
• Adopt crypto-agility — design systems so algorithms can be swapped without a rewrite.

The window is now

Migrations of this scale take years. Waiting for a working quantum computer before acting is the one strategy guaranteed to fail. We research and design quantum-resistant schemes so that the data you protect today is still safe after Q-day.
