Announcing the preliminary program for Cedarcrypt — our inaugural applied cryptography summer school and conference, July 13–16, 2026 at the American University of Beirut - Mediterraneo in Paphos, Cyprus! We've put together a program we're genuinely proud of — a pedagogical progression from accessible foundations to state-of-the-art constructions, featuring lectures, hands-on workshops, and research talks from leading voices across academia and industry. The program spans everything from accessible foundations to cutting-edge research: Bart Preneel (KU Leuven) opens with a keynote, followed by deep dives into FHE with Emad Heydari Beni (Nokia Bell Labs), state-of-the-art hash-based SNARKs with Giacomo Fenzi (EPFL), and Zero-Knowledge Proofs with Tarek Galal (TU Berlin). Practitioners will hear from Zeke Hunter-Green how The Guardian built their anonymous whistleblowing system (CoverDrop MLS), and a host of other guest speakers who will help attendees learn post-quantum migration strategies across lattices, isogenies, and codes, and get hands-on with threshold signing, MPC engineering, and constant-time programming — all in four days on the Mediterranean coast. Organized in collaboration with the IACR, and hosted on Cyprus's Mediterranean coast — a UNESCO World Heritage city where you can step from a workshop on threshold signing straight to a seaside taverna. Thanks to our generous sponsors — Electi, PQShield, Symbolic Software, Zama, and several anonymous donors — we're offering FULL SCHOLARSHIPS (travel lodging) to students and early-career researchers, awarded on a rolling basis until funds are exhausted. Graduate students, early-career researchers, and practitioners in applied cryptography: we built this for you! Join us this July in sunny Paphos! Let's make this an inaugural event to remember!

« Certes violé constamment » c’est un truc de fou furieux d’être un humain aussi faible et détestable que lui
🇫🇷🇮🇱🇵🇸🏛️ LUNAIRE !! « Il y a désormais un cessez-le-feu à Gaza, certes imparfait, certes violé constamment, mais qui existe. » lance Jean Noel Barrot 👉 Pour rappel, près de 1 000 Palestiniens ont été assassinés à Gaza depuis le début de ce qu’on présente comme « un cessez-le-feu. »

The War stole my life.💔 2023 2026
Guess who made it through two years of genocide and finally graduated high school after a two-year delay because of the war on Gaza.

My applied cryptography course's summer semester started up this week. Here's an email I received yesterday from a student. I think that people should see this.

While the usual minions spread new falsehoods about fellow UN experts and me, here is what Israel and its supporters want absolutely you not to see. The body of evidence. Warning: highly disturbing content. youtube.com/watch?v=e3pApprH…

If you watch anything today, watch this Palestinian man's testimony about what's happening in Israeli prisons. UPDATE They released him over a year ago and we heard he had been abducted AGAIN because he spoke out about Ben Gvir putting him in a black plastic bag and dancing on his body. We don't even know if he's still alive.

Richard Burgon just exposed the most glaring double standard in British policy "Imagine if this weekend in London there was a Russian real estate event selling Ukrainian land. The government would ban it immediately. Instead, we have an Israeli real estate event openly advertising the illegal sale of land in occupied Palestinian territories. The government recognizes Palestine. Why isn't this banned?"

🚨‼️Israel is casually kidnapping civilians in southern Lebanon. Two more men were abducted today while operating a well in Kfarchouba, the only source of water for the area. This brings the total number of civilians abducted from Kfarchouba alone to six. The Sunni-majority village is among the few communities within the "yellow line" that remain inhabited. The mayor told us Israeli raids and abductions have become a constant threat. “This is our land and our country. We will not leave. They can use force and intimidation, but they cannot break our attachment to our land, our homes and our village.” thenationalnews.com/news/men…
