🔵 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-… #imdea #imdeasoftware #bitcoin @educacmadrid @ComunidadMadrid @IMDEAInstitutes

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
