(1/8) I am very happy to announce askcryp.to, a non-commercial platform to discuss and ask questions about Cryptology ePrint Archive papers. It aims to accumulate knowledge around papers in cryptography.

#ePrint Functional Commitments for Circuits from Falsifiable Assumptions: D Balbás, D Catalano, D Fiore, RWF Lai ia.cr/2022/1365

#ePrint Cryptographic Administration for Secure Group Messaging: D Balbás, D Collins, S Vaudenay ia.cr/2022/1411

¡Nuevo desafío criptográfico en EL PAÍS Tecnología! En esta ocasión David Balbás y Diego Castejón, de IMDEA Software nos retan a salir de una Escape Room 🚪usando un ⌨️ manipulado ¿Lo conseguiremos? Bernardo Marín elpais.com/tecnologia/202…

Cerramos hoy nuestros Desafíos criptográficos con la solución del último reto. Mil gracias a todos los "desafiantes", a los intrépidos "desafiados" y a Bernardo Marín por llevar el timón! 👏👏👏 elpais.com/tecnologia/202… vía EL PAÍS

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 (David Balbás and Daniel Collins) will be there in a few weeks to present our research. #USENIX2023

Excited to share that our paper on Sender Keys: "WhatsUpp with Sender Keys? Analysis, Improvements and Security Proofs" has been accepted at ASIACRYPT! Grateful to my incredible coauthors Daniel Collins and David Balbás for their hard work. 🧵

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

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. 🚀

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/

David Balbás presenting our paper on Sender Keys at #Asiacrypt in Guangzhou. Timely, as Facebook Messenger adopts the Sender Keys protocol. Joint work with David Balbás and Daniel Collins. [Paper: ia.cr/2023/1385] [Messenger update: about.fb.com/news/2023/12/d…]

🔵 A group of researchers from #IMDEASoftware, UC3M, and NEC Laboratories Europe create innovative verification techniques to increase security in artificial intelligence and image processing. The research is part of the #PICOCRYPT project - European Research Council (ERC) 🌐 c.madrid/wwzft #ERCCoG

Great work lead by David Balbás within the #picocrypt project headed by Dario Fiore 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

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…
