Quantum computers threaten current encryption by making RSA and ECC breakable via Shor's algorithm. The 'harvest now, decrypt later' attack means adversaries can store encrypted data today and decrypt it once quantum hardware matures. Lattice-based cryptography, specifically the Learning with Errors (LWE) problem, offers quantum-resistant security because no known quantum shortcut exists for high-dimensional lattice problems. NIST finalized two standards in 2024: ML-KEM (FIPS 203, based on CRYSTALS-Kyber) for key encapsulation and ML-DSA (FIPS 204, based on CRYSTALS-Dilithium) for digital signatures. A practical migration roadmap is outlined: build a Crypto Bill of Materials, prioritize sensitive assets, swap in ML-KEM and ML-DSA, and design for crypto agility to enable future algorithm swaps without rewriting core systems.
