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!

Our beautiful "DiStefano" - a zkTLS protocol- paper (with Hamed Haddadi, Alex Davison, Gonçalo Pestana and Joe Rowell) just won Distinguished Paper Award at @NDSSSymposium ! eprint.iacr.org/2023/1063.pdf Such an honour! Upcoming work as part of Brave coming!!

Very excited to share our first exploration of threshold MAYO (yes, the PQC algorithm)! 🎉 Joint work with the amazing
Daniel Escudero and Guilhem Niot. The ideas can extend to UOV as well—let’s have MV-based threshold cryptography!

Read some of the details of the DiStefano protocol (a ZKTLS or DCTLS one lnkd.in/eMfwh8za) from Brave: we also share some news on new work of attesting HTML or JSON in ZKP, and AES in ZKP ;) Expect some upcoming work on it! We will be presenting DiStefano at NDSS 2025!

Binary Fuse Filters are an amazing construction introduced by Thomas Mueller Graf and Daniel Lemire in arxiv.org/abs/2201.01174. Using them we arrive to 6×-11× more efficiency than state of the art ;)

New paper! Together with Alex Davidson, we introduce 'Chalamet' a keyword-based PIR scheme! eprint.iacr.org/2024/92 We also introduce a framework so that any index LWE-based PIR scheme can be transformed to keyword-based via the usage of binary fuse filters

Second time speaking at the UN! (not so nervous as last time). Let's talk about human rights and protocol design ;)

Wow!! Our paper "Practically-exploitable Cryptographic Vulnerabilities in Matrix" got the Distinguished Paper Award (DPA) at @IEEESSP, 2023. So wonderful! Happy for my co-authors @malb.bsky.social @DowlingBJ @djwj_ and this amazing work!
