What is Quantum-Resistant Cryptography?. Quantum‑resistant cryptography uses algorithms believed to be secure against quantum computers, which could break some current schemes.
How it works
Post‑quantum signatures and key exchanges replace or augment classical methods; migration plans evolve ahead of practical quantum threats.
Why it matters
Long‑lived data and assets may need protection today to remain safe in the future.
Common pitfalls
- Waiting for a quantum event before planning
- Using experimental schemes without review
- Ignoring performance impacts
Quick example
A custody provider pilots post‑quantum keys for high‑value cold storage.
