Transitioning critical infrastructure and communication systems to quantum-resistant cryptographic algorithms to protect against future quantum computer attacks.
Transitioning critical infrastructure and communication systems to quantum-resistant cryptographic algorithms to protect against future quantum computer attacks.
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.
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.
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.
