#eurocrypt — Public Fediverse posts

Hey! If you're at Eurocrypt and do not have a CedarCrypt flyer yet do not talk to @nadim.computer , come talk to me instead! I have a deal with Nadim: if I manage to hand over all the flyers he gave me to people who still don't have one, he will join Mastodon! I have only 4 flyers left! We can do this! F**k BlueSky! 😜

#eurocrypt just happened, which reminds me of the eurocrypt 35 years ago held in budapest, which an #NSA cryptologist was attending and giving a scorching #report in the internal cryptolog newsletter of the nsa: https://scottaaronson.blog/?p=2059

would be interesting to see the latest cryptolog report on this latest edition...

Our paper https://ia.cr/2026/913 shows how to find affine maps agreeing with an S-box on as many as possible inputs. Look for presentation at #Eurocrypt 2026 today!

The code is already available. Also check out a vide-coded interactive tool, it's fun to play with: https://affine.group/pages/greedy-extension

At #Eurocrypt where we'll be presenting my work on FLOE!

Our paper about cryptanalysis of AIM2 is on the front page of eprint 😀 Look for tomorrow's presentation at #Eurocrypt 2026. I will share more details later. https://ia.cr/2026/903
