We're organizing a workshop on cryptographic group actions bringing together the isogeny and code communities. The workshop is just before Eurocrypt, a quick train away from Rome in the beautiful Marche.
Early registration ends this week, so grab your spot soon!

I am very happy to announce that thanks to the hard work of many people (The "MIKE Team"), we now have a working implementation in SageMath of MIKE (Module Isogeny Key Exchange).

Do you use a cloud-based password manager? So what's your threat model?
Vendors like Bitwarden, Dashlane, LastPass and 1Password offer you "Zero Knowledge Encryption", with statements like: "Not even the team at Bitwarden can read your data (even
if we wanted to)."
We decided to test this… 1/n

We're hosting an Autumn School in London, UK, from 15 to 17 September 2026, to bring together ethnographers and cryptographers to discuss ways in which the two fields can be meaningfully brought into conversation. This is also the premise of our Social Foundations of Cryptography project: to ground cryptography in ethnography. Here, we rely on ethnographic methods, rather than our intuition, to surface security notions that we then formalise and sometimes realise using cryptography. Our intention is to 'flip' the typical relationship between the computer and social sciences, where the latter has traditionally ended up in a service role to the former. Rather, we want to put cryptography at the mercy of ethnography. But how do we do this? How do we as cryptographers interact with and make sense of ethnographic field data? How can we refine, improve or extend this interaction? What obstacles do we face when we make cryptography rely on ethnographic data which is inherently 'messy'? How do we handle that cryptographic notions tend to require some form of generalisation but ethnographic findings can only be particular? How do ethnographers retain the richness of ethnographic field data in conversations with cryptographic work? Indeed, our project has already highlighted some limitations of our approach. It has brought to the fore concrete challenges in 'letting the ethnographic data speak' while still making it speak to cryptography. The Autumn School is an opportunity to explore these questions jointly across ethnography and cryptography, through a series of talks, group discussions and activities. We say a bit more about the programme and registration for the Autumn School here.

New paper out! 🎉
We translate the algebraic group model to the (generic) isogeny setting, generalising previous results that were limited to oriented isogenies (we show that any result that holds in the AGAM also holds in the AIM).
Using this model, we obtain two important results:

Crazy!
I grew up just below the Sanctuary: I could see it from my childhood room's balcony, perched up there on the mountain. It's my go-to cycling spot any time I go back. I am deeply aware of the juta pilgrimage, and yet I'd never heard of the juta dei femminielli.

Interested in the security of MPC implementations?
Peter Scholl (@schollster.bsky.social) and I are looking for research interns to study the theory/practice gap for MPC. We can host multiple interns in Aarhus for the summer 2026.

Yes! It was me!
I stole the key from Moti's hard drive and wiped it 😈

Slide titled “How can researchers regain control of publication?” by Marie Farge (from a talk given on 2025-09-02 in Milan at the International Conference on Optimization and Decision Science).
These very nice slides by Marie Farge on how researchers can regain control of publication have been brought to my attention: openscience.ens.fr/MARIE_FARGE/... — I think they're worth spreading more widely!
Got an invitation to review for a journal that charges > 3 k$ in APC. How much should I charge for the review?
