The PQC Landscape: Protocols and Standards
summary
NIST names three PQC standards in 2024 and adds HQC as the round‑four winner in 2025, while SP800‑227 codifies how KEMs are used in protocols. A contentious seed vs expanded key compromise now allows storing private keys as a small seed or as seed+expanded sequence (ASM1). Practical gaps get fixed: certAnchor proof‑of‑possession for KEMs and published composite certificates for hybrid migration; one PQC candidate (psyc) is broken in ~2 hours on a laptop.
