There is still time to submit your proposals for affiliated events! The call is open until tomorrow December 6th, 11:59 (AoE). #EC25 #Eurocrypt25
🔵 El investigador de IMDEA Software, Diego Castejón, publica en @Conversation_E el artículo ➡️ ¿Alguien sabe a quién mandé mi criptomoneda? 🔎 En una criptomoneda como Bitcoin, cualquiera puede saber quién paga a quién. Una de las herramientas disponibles para mejorar la privacidad son los mezcladores de monedas. Con ellos, un conjunto de remitentes y destinatarios pueden esconder sus relaciones financieras de cualquier observador indiscreto. 🌐 theconversation.com/alguien-sabe-a… #imdea #imdeasoftware #bitcoin @educacmadrid @ComunidadMadrid @IMDEAInstitutes
Este jueves arrancamos CryptoClub en la @uc3m, una iniciativa compartida con @0xjet para reunir a alumnos e investigadores junior interesados en aprender sobre criptografía y seguridad..¿Os animáis? sites.google.com/view/cryptclub…
Cryptograhers and cryptography enthusiasts - follow @IACReurocrypt for updates on Eurocrypt 2025! #EC25 #Eurocrypt
Hola! In this account, we will post information and updates on the EUROCRYPT 2025 conference, which will be held from May 4 to 8 in Madrid, Spain. Follow us and share with your network! #IACR #Eurocrypt #EC25

I am looking for a PhD student in Cryptography to join our group at @IMDEA_Software ! Topics of interest include zero-knowledge proofs, succinct proof systems and verifiable computation, computation on encrypted data. For more information -> software.imdea.org/careers/2024-0…
Great work lead by @dabalbas within the #picocrypt project headed by @dariofiore0 at @IMDEA_Software 🙌🙌 La Comunidad de Madrid crea técnicas de verificación para aumentar la seguridad en el uso de la Inteligencia Artificial shar.es/agtIdS
🔵 A group of researchers from #IMDEASoftware, @uc3m, and @NECLabsEU create innovative verification techniques to increase security in artificial intelligence and image processing. The research is part of the #PICOCRYPT project - @ERC_Research 🌐 c.madrid/wwzft #ERCCoG
@dabalbas presenting our paper on Sender Keys at #Asiacrypt in Guangzhou. Timely, as Facebook Messenger adopts the Sender Keys protocol. Joint work with @dabalbas and @dcol97. [Paper: ia.cr/2023/1385] [Messenger update: about.fb.com/news/2023/12/d…]
Announcing PQXDH! The first step in post-quantum resistance for the Signal Protocol, PQXDH protects your Signal calls & chats from potential future threats of breakthroughs in quantum computing. And it's already rolling out to Signal clients everywhere. signal.org/blog/pqxdh/
2/2: Our research introduces Sender Keys+ a refined protocol, balancing security and performance. This is the continuation of our work at RECSI 2022. Stay tuned for the ePrint. #SenderKeys+ #fromSantanderToGuangzhou. 🚀
1/2: Developing encrypted group messaging solutions remains a challenge. Apps like WhatsApp employ the Sender Keys protocol, yet it lacks formal study. Our work bridges this gap with a fresh security model & analysis, revealing several shortcomings. 📚 #SenderKeys
I'm pleased to share that our poster entitled "WhatsUpp with Sender Keys? Analysis, Improvements, and Security Proofs" has been accepted at USENIX 2023. My two brilliant co-authors (@dabalbas and @dcol97) will be there in a few weeks to present our research. #USENIX2023
