dl.acm.org/doi/10.1145/38… NIST標準化にてML-KEMのバックアップとして選定されている符号ベースKEM (Hamming Quasi-Cyclic (HQC)) の実装効率改善. HQCのボトルネック（多項式演算など）をAVX-512で最適化し, 最大約1.5–1.6倍高速化を達成. その結果, ML-KEMとの性能差を約9.5倍→5.6倍まで縮小.

Recent advances in quantum hardware and software have accelerated the timeline on which quantum attack might happen. Cloudflare is responding by moving our target for full post-quantum security to 2029. cfl.re/4v674Oi

We've been crowdsourcing a list of "fancy cryptography" used at scale in production. For two reasons: first it's amazing to see how much this is actually in use today. More importantly, most of it is not post-quantum, and this gives researchers a great resource for future work!

Post quantum signatures are too large. But we have a solution: Merkle Tree Certificates. Last week we announced we’re trying this out with Chrome to see if it works at scale. At the same time we’re bringing these ideas to the @ietf.

Cloudflare is launching an experiment with Chrome to evaluate fast, scalable, and quantum-ready Merkle Tree Certificates, all without degrading performance or changing WebPKI trust relationships. cfl.re/42YD7Ua

On preparation for #latincrypt, students from the Americas joined in a very interactive session about the hotest topics in Cryptography. For me, I really enjoyed to participate as a facilitator. Thanks to @octaviopk and @hdvanegasm for the invitation.
Hernán Vanegas@hdvanegasm

CatioCrypto, the cryptography school in Spanish affiliated to LatinCrypt 2025, was a success! Thanks to @octaviopk for coordinating this with me, and to the speakers Armando Faz-Hernandez, Valerie Gilchrist, and Eduardo Soria-Vazquez. Also, thanks to the LatinCrypt organizers.
