What is Quantum-Resistant Cryptography in Cybersecurity?
Quantum-resistant (post-quantum) cryptography refers to algorithms designed to withstand attacks from quantum computers. Shor's algorithm could break RSA and ECC by factoring large numbers efficiently. NIST selected CRYSTALS-Kyber for key exchange and CRYSTALS-Dilithium for digital signatures as initial post-quantum standards in 2024.
Why Quantum-Resistant Cryptography Matters for Your Cybersecurity Career
The "harvest now, decrypt later" threat means adversaries already collect encrypted data hoping quantum computers will eventually break it. Security architects must plan cryptographic migration timelines. CISOs need to inventory cryptographic dependencies across their organizations. Understanding post-quantum readiness is becoming a requirement for senior security roles.
