🔵 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.

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

[Phillip @p4i11ip]

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 @dcol97 and @dabalbas for their hard work. 🧵

[Phillip @p4i11ip]

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
