Post-Quantum Cryptography (PQC)



Quantum Apocalypse: Store Now, Decrypt Later (DNDL) ... stealing data now to decrypt it in future, as quantum computing could render modern encryption methods obsolete



NIST Standardization process for PQC

  • Post-Quantum Cryptography (PQC) | NIST
  • NIST winners and will ratify standards in 2024
  • Multiple global rounds since 2015 led to NIST announcing winners in July 22 - four algorithms:
    • CRYSTALS-KYBER was chosen by NIST as the new standard for public-key encryption/KEMs
    • Falcon, CRYSTALS-Dilithium and SPHINCS+ will all be standardized for digital signatures
  • There are more algorithms under consideration too, so the process continues
