Post-Quantum Cryptography
The quantum computing era is approaching. Learn how quantum-resistant algorithms protect your data against Shor's algorithm and the harvest-now-decrypt-later threat.
What is PQC?
Post-Quantum Cryptography (PQC) refers to cryptographic algorithms designed to be secure against attacks by quantum computers. Unlike current public-key algorithms like RSA and ECC, which rely on the difficulty of factoring large numbers, PQC algorithms are based on mathematical problems (like lattices) believed to be resistant to quantum attacks.
"In August 2024, NIST published the first three finalized PQC standards: FIPS 203 (ML-KEM), FIPS 204 (ML-DSA), and FIPS 205 (SLH-DSA)."
The Threat Model
Classical RSA-2048
Can be broken by a cryptographically relevant quantum computer in hours.
NIST ML-KEM (Kyber)
Designed to remain secure even against powerful quantum adversaries.
NIST Finalized Standards
FIPS 203 (ML-KEM)
Formerly Kyber. A key encapsulation mechanism for secure key exchange in TLS and VPNs.
Primary StandardFIPS 204 (ML-DSA)
Formerly Dilithium. A module-lattice-based digital signature algorithm for identity and auth.
Auth & SigningFIPS 205 (SLH-DSA)
Formerly SPHINCS+. A stateless hash-based signature algorithm as a conservative backup.
