What is Post-Quantum Cryptography in Cybersecurity?
Cryptographic algorithms designed to resist attacks from both classical and quantum computers. NIST finalized its first PQC standards in 2024, including ML-KEM for key encapsulation and ML-DSA for digital signatures. These algorithms replace vulnerable RSA and ECC schemes with lattice-based, hash-based, or code-based mathematical structures.
Why Post-Quantum Cryptography Matters for Your Cybersecurity Career
Every organization using public-key cryptography will need to migrate to PQC algorithms. Security engineers must inventory cryptographic dependencies and plan transitions. Security architects selecting new protocols and products should already require PQC support. This will be a multi-year effort across the entire industry.
