Status report on Post Quantum Cryptography Standardization
summary
NIST announces concrete choices and a timeline: Kyber KEM plus signature options Dilithium and Falcon and the hash‑based SPHINCS+ mapped to five security levels (levels 1/3/5 ≈ AES‑128/192/256). Public keys range roughly 1–12 KB for Kyber, encapsulation ≈46k/s and decapsulation ≈6k/s in software, Dilithium pubkeys ≈1–2.5 KB, Falcon trades tiny signatures for large private keys, SPHINCS+ gives tiny pubkeys but very slow signing. Draft standards appear soon and final standards target 2024, call for new signatures closes June 1, discussions include hybrids, patents, and side channels.
