Post-quantum cryptography migration is not something to postpone until quantum computers arrive. In this Elektor TV clip from the Elektor Academy Pro Post-Quantum Cryptography conference, Klaus Schmeh explains why long-lived embedded systems, secure devices, credentials, and firmware update chains may require action years before "Q-Day" — the moment when quantum computers can threaten today's cryptography. With NIST's first post-quantum cryptography standards now finalized, the challenge is no longer just choosing new algorithms, but understanding where cryptography is embedded throughout a product and planning the migration path.
