The call for talks for CAW 2026 (a workshop affiliated with Eurocrypt) is out! This year's motto is "cryptography under real-world constraints and threat models", but other applied cryptography is also very welcome. All info is on: caw.cryptanalysis.fun.

My article on 'cute surveillance' is now out Literature: Journal of C21st Writings 'Cute Surveillance: Embodiment, Subjectivity, and Intimacy in Samanta Schweblin’s Little Eyes' Open access here: c21.openlibhums.org/article/id/1...

📣 Germany's close to reversing its opposition to mass surveillance & private message scanning, & backing the Chat Control bill. This could end private comms-& Signal-in the EU. Time's short and they're counting on obscurity: please let German politicians know how horrifying their reversal would be.

I've signed this too. AI reaching parity with humans next year!? Maybe Altman et al aren't impartial predictors ...

So excited to be speaking at #MozFest about feminist cyberlaw futures! We’ll be reacting and redacting (!) our way to unlearning cyberlaw narratives. Download our redaction tool here: tepski.tech/feminist!

Dismantling the Institutional Review Board (IRB), that oversees all human subjects research, is bad. Really bad.

Decrying violence against political opponents rings a bit hollow when you pull Secret Service protection from your political opponents.

Woo!! Coral goes to S&P! eprint.iacr.org/2025/1420 Coral is an amazing system to check over ZKP that a document conforms to a grammar (JSON, C, TOML). Super happy with this work and the amazing work of all the co-authors!

a fantastic video about important topics and with a worthy fundraiser, and best of all it has this amazing moment

Two super nice things this week!! Thank you, AsiaCCS (really happy there are such things as reviewer's awards, as we need good reviews!) and @iacrcrypto.bsky.social !

Anyone who has been an IACR member in 2023-2026 should have received a link to respond to a survey about conferences and publishing. So far over 500 people have responded, but it will remain open for responses until Sept 12, 2025. I would also encourage people to use their forum invitations.

USENIX chair report: "six individuals appear as co-authors on 20 or more submissions, with two authors appearing on 36 and 39 submissions respectively. At such volume, it becomes difficult not to question the nature and depth of the contributions" www.usenix.org/sites/defaul...

I just learned that Claus Schnorr passed away last June, aged 81 — a significant loss for the cryptographic community: mittelhessen-gedenkt.de/traueranzeig...

We sent a letter to all superintendents in Arkansas warning them not to display the Ten Commandments in schools after a federal judge this week ruled that a state law requiring the displays is “obviously unconstitutional.” Every school district has an obligation to abide by the First Amendment.

Proud of this work, and of the amazing work of Eli!

Just as it did with the Apple "backdoor" demand, the UK Government has got itself into a ridiculous mess over age estimation and VPNs. Here's a Govt spokesperson saying that young users must not be encouraged to use VPNs. 1/n

Single author, fifteen pages, reduces the bit complexity of millenia-old UOV instances!!

Yikes. Turns out you can send a plaintext radio signal to cause any train in the USA to do an emergency break. The original 'security' was just a checksum, no encryption or authentication. Reporting this took them 12 years (!) because the vendor dismissed it initially www.cisa.gov/news-events/...

Starting July 25, Bluesky will require users in the UK to scan their face, upload an ID or verify their identity with a bankcard. I realize that platforms feel they have no choice but to comply with the government surveillance schemes, but shocking nonetheless.

We (finally) published all the material from this course on SQIsign, including lecture slides and exercise sheets for the Sage laboratory. Available here: github.com/andreavico/S...
