The quantum computing threat to current cryptographic systems is no longer a theoretical concern. Organizations face an urgent need to transition to post-quantum cryptographic algorithms.
The Quantum Threat
Quantum computers, when sufficiently powerful, will break RSA and elliptic curve cryptography. The "harvest now, decrypt later" threat means sensitive data is vulnerable even before large-scale quantum computers exist.
The Standards
NIST has finalized several post-quantum cryptographic standards: ML-KEM (CRYSTALS-Kyber) for key exchange, ML-DSA (CRYSTALS-Dilithium) for digital signatures, and SLH-DSA (SPHINCS+) as an alternative.
The Migration Challenge
The transition is one of the most significant cryptographic migrations in computing history, requiring updates to protocols, libraries, hardware, and operational practices.
Getting Started
Organizations should inventory cryptographic assets, assess risk, plan migration, and test compatibility — beginning preparation now even if full migration is years away.
