Vietnam's Government Cipher Committee Publishes Three Draft Post-Quantum Cryptography Standards on 17 October 2026: Home-Grown HB-PQSign Beside ML-KEM and ML-DSA, on a 2027 to 2035 Roadmap

Vietnam's Government Cipher Committee, the military-ranked agency under the Ministry of National Defense, published three draft national post-quantum cryptography standards in Hanoi on 17 October 2026: a home-grown hash-based signature, HB-PQSign, beside ML-KEM and ML-DSA. Decision 125/QĐ-TTg sets standards by 2027, hybrid integration by 2030, QKD as an auxiliary technology and full transition of critical systems by 2035. What the drafts establish for a defense buyer, and the dual-stack crypto-agility question they raise for vendors.
