Understanding a known-plaintext attack . A known-plaintext attack (KPA) occurs when a hacker uses pairs of both encrypted and unencrypted data to figure out the encryption algorithm or key.

NIST announced three of the four proposed quantum-resistant encryption algorithms this week: CRYSTALS–Kyber, CRYSTALS–Dilithium, and SPHINCS+. The fourth one, FALCON, might be released next year.

Quantum computers may soon be able to crack encryption methods in use today, so plans are already under way to replace them with new, secure algorithms. Now it seems the US National Security ...

In July that year, NIST selected four encryption algorithms to become part of the agency’s post-quantum cryptographic standard. At the time, Secretary of Commerce Gina M. Raimondo welcomed the ...
