The Information-Theoretic Cryptography Conference (ITC 2026) paper deadline is now March 16 AoE and the submission server is up. itc26.hotcrp.com Colocated with Crypto at UCSB (August 15-16, Sat-Sun), great invited talks and PC chair @zaumka. Please submit your best work!

Our paper on our crypto-agnostic consensus protocol Juggernaut was accepted at Eurocrypt 2025! Check out Yuval's thread and our paper for more details.

Imma makin twitter threads now I guess. New paper! With @jovan_komatovic @dcol97. Juggernaut is a protocol that enjoys all the benefits that cryptography offers to consensus, while remaining secure even if this crpytography is broken! (1/n) eprint.iacr.org/2024/1601

This is an amazing paper by Leah Namisa Rosenbloom on extending the dialogue of 'The Moral Character of Cryptographic Work': eprint.iacr.org/2024/1602.pdf

this is what it feels like

@CISPA @BochumCrypto @julian_loss Well deserved :)

Africacrypt 2024: the keynote speakers are here: @luca_defeo, @BetulFDurak and @AtsukoMiyaji !! Don't forget to book your ticket for the event at : africacrypt2024.com. Early registration runs till May 31st. See you in Douala 🎉🎉🎉🎉!

I co-authored a new open letter signed by more than 270 scientists from 33 countries warning for the risks of the modified CSAM (child sexual abuse) regulation proposed by the Belgian presidency. #chatcontrol csa-scientist-open-letter.org A🧵1/10

Huge congrats to Dr. @dcol97 for defending his PhD with flying colours! 🎉 Your work on secure messaging has been awesome and it's been a pleasure collaborating. Keep up the great work!

I had hoped that the EU was going to abandon its plans for mass content scanning. But apparently the EU Presidency has made some meaningless changes, and now the bill looks set to pass in June. netzpolitik.org/wp-upload/2024…

Dear Crypto Bubble, I'm looking for motivated applicants for my PhD position: - Research on privacy preserving messaging - Fully funded - Interdiscipl. research group - Joint supervision by PI team - Apply ≤ April 10 - Starts in October - Nuremberg is nice & a climbing paradise

@isislovecruft @matthew_d_green I believe eprint.iacr.org/2022/1703 was the first (quantamagazine.org/cryptographers…)

Every now and then something really amazing happens in cryptography and finding those events makes everything else worthwhile.

@SolalPirelli @pastrychaser @thisishaoqian @MartinVetterli @EPFL Regardless of whether he's in the 'right' about his overtime claim, don't you think we should support him as fellow students for doing something that is very risky and vulnerable in the face of EPFL management, or do you think we should just stand back and judge?

@pastrychaser @thisishaoqian @MartinVetterli @EPFL Do you have info the rest of us don't or are y'all reflexively siding with someone without knowing the situation? And I mean this also for people who sided with HR, presumably they don't have secret information either?

This email was delivered and read by people and then EPFL deleted it from people’s inbox without their consent. Please spread to the world. This is about freedom of speech and personal data protection. @MartinVetterli @EPFL

@thisishaoqian Full support for your actions

It seems that my second email was deleted by EPFL. I can not believe this is happening in Switzerland.

Hey, did you miss the Santa Barbara deadline? Did you wake up after the submission deadline this morning? No worries! Africacrypt 2024’s submission deadline has been postponed to March 1st 2024 anywhere on earth. Visit africacrypt2024.com for more.

The full version of our paper on post-quantum X3DH key exchange, accepted at USENIX Security 2024, is now online! Our protocol K-Waay uses a Frodo key exchange-based split-KEM rather than ring signatures and is therefore very fast. ia.cr/2024/120 @KhanhCrypto @SVaudenay
