Post-Quantum Cryptography Migration
Transitioning critical infrastructure and communication systems to quantum-resistant cryptographic algorithms to protect against future quantum computer attacks.[1]

What is the problem?
Large-scale quantum computers will break widely used public-key cryptography schemes like RSA and elliptic curve cryptography using Shor's algorithm. Current encrypted data can be harvested now and decrypted later once quantum computers are available.
How does quantum computing help?
Implementing NIST-standardized post-quantum cryptographic algorithms based on lattice problems, hash functions, and code-based cryptography. These mathematical problems remain hard even for quantum computers. Organizations are deploying hybrid classical-PQC solutions during the transition period.
What are the results?
NIST finalized PQC standards in 2024 (CRYSTALS-Kyber, CRYSTALS-Dilithium, SPHINCS+). Major technology companies and governments are actively migrating systems. Financial institutions and defense sectors are prioritizing high-value data protection.
