Hello Bluesky! I did a thing and now I am the proud owner of the greatest hat in the world! 🎓

At least we can still sit on a Cray-1. Today’s invisible infrastructure will end up being scrapped in the blink of an eye.

This is a friendly reminder that the call for contributed talks to Real World Crypto in Taipei 2026 is open until October 10. We are looking for interesting talks bridging cryptography and its real-world use! Also it’s a great way to meet new people! rwc.iacr.org/2026/contrib...

It would be super useful to have Claude ingest a paper and try to reproduce (some of) the results. I tried it once and it completely failed to get the point.

We found a new vulnerability in TLS. It's a variant of the ALPACA attack that bypasses current countermeasures. Relativly low impact - but great insight! Check it out: opossum-attack.com

Man lese und lösche umgehend seinen Twitter-Account, falls immer noch nicht geschehen.

Unfaßbar, was @arminwolf.at versucht hat und wie er an X, den Iren, der EU und (natürlich) an den USA scheitert.

That’s going to be your first and half of your last slide, right?

Eamonn and I received a Zama Cryptanalysis Grant to help with the lattice estimator github.com/malb/lattice.... We hope to hire interns to work on the estimator over two periods over the next 18 months.

Zama are still taking applications for this grant, see here: www.zama.ai/post/announc...

It’s a quote attributed to William Faulkner: „In writing, you must kill all your darlings.“ I find I have to remove about half of what I initially include in a text, sometimes more, to make room for the essence to shine. ✨

Kinderschutz im Netz bleibt oft Theorie: Informatikerin Veelasha Moonsamy untersuchte mit Kolleg*innen aus Belgien und den Niederlanden rund 70.000 Werbeanzeigen auf Webseiten für Kinder – mit alarmierenden Ergebnissen.

Als Mitglied des Exzellenzclusters CASA erforscht @veelasha.bsky.social die Systeme unseres alltäglichen Gebrauchs, wie etwa unsere Smartphones. Am 22. Mai entscheidet sich, ob CASA und damit die Forschung von Moonsamy und ihren Kolleg*innen weiter gefördert wird. Daumen drücken! 🤞

I could never. 1kg/week is a 1000kcal deficit per day, every day, for me: being a zombie for two months. I cap it at 500g/week. Wish you the best!

Well, I‘m European so I guess we are making an inventory assessment and migration plan that makes the Pqc migration look like child‘s play.

Update on crypto.iacr.org/2025/

Given recent instances of US visa holders and residents being detained or deported by US immigration authorities, we understand that some members of our community may not feel safe traveling to the US for Crypto this year. We want to assure everyone that we will provide the option to present and attend remotely.
