Guy asks about what would happen if lattices and codes got broken.

After people panel outlines some non great but workable alternatives, asks about #QKD. Immidiately gets shot down.

It's bullshit and all cryptographers know it! #rwpqc

Panel discussion about the post quantum transition.

In general the term transition was mentioned a lot today.

I notice that I am very much more used to hearing it in a very different setting...

Just in time for Real World PQC Workshop:

I took at a look at who currently supports #PQC. The answer will not surprise you at all.

Came for Real World Crypto and the #RWPQC workshop, but Sofia sure looks nice with or without the crypto.

Just a heads-up that at the end of March there is a "crypto week" in Sofia, Bulgaria, with a ton of co-located cryptography-related events. I will also give a talk on Shufflecake at OSCW.

I will be around, planning of attending at least ZKProof, ZK Hack Meetup, RWPQC, OSCW and RWC.

New talk! Shufflecake will be presented at the Open Source Cryptography Workshop 2025 in Sofia, Bulgaria, on 2025-03-25. OSCW is co-located with Real-World Crypto 2025 and a plethora of other crypto events. Stay tuned!

Mélissa Rossi from the French ANSSI position on hybrids:
"ANSSI strongly recommends avoiding any drop-in replacement of pre-quantum with post-quantum. (exception: hash-based signatures)”
Recommending hybridization.
#RWPQC

Is there a Five Eyes-level agreement to not use hybrids? #RWPQC

Lessons learned from Vadim Lyubashevsky at #RWPQC: “Large [research] teams do not imply lots of people checked correctness”
People feel less accountable than if it's a smaller team. Really need a lot of outside checking. Outsiders have more incentives to find mistakes than group members.
