cMixx es una mixnet muy r\u00e1pida. En t\u00e9rminos m\u00e1s generales, las mixnets, tambi\u00e9n conocidas como redes de mezcla, fueron descritas por primera vez por David Chaum, fundador de xx network, en 1979. Una mixnet establece reglas criptogr\u00e1ficas para que los mensajes o transacciones sean retransmitidos por una secuencia de intermediarios de confianza conocidos como nodos mixtos. Estos nodos mixtos reciben un lote de datos cifrados de los usuarios, los permutan o \"mezclan\" aleatoriamente y env\u00edan los datos reordenados y cifrados al siguiente nodo mixto.<\/span><\/p>\n

Esta \"mezcla\" oculta los metadatos asociados a la actividad del usuario, creando un sistema de comunicaci\u00f3n que protege la privacidad. Los metadatos son los detalles de qui\u00e9n, qu\u00e9, cu\u00e1ndo, d\u00f3nde y c\u00f3mo asociados a cualquier mensaje o actividad.\u00a0<\/span><\/p>\n

El principal inconveniente de las redes mixtas existentes es que las operaciones de clave p\u00fablica necesarias para la operaci\u00f3n de mezcla requieren un c\u00e1lculo intensivo. De hecho, en 1979, los c\u00e1lculos descritos originalmente en el art\u00edculo de Chaum superaban la potencia de la mayor\u00eda de los ordenadores existentes. Incluso ahora, los c\u00e1lculos necesarios para las redes mixtas t\u00edpicas consumen muchos recursos y tiempo. Por eso, cuando se realizan a gran escala, las redes mixtas son demasiado lentas para la mayor\u00eda de los consumidores.<\/span><\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

En 2016, Chaum y un equipo de investigadores publicaron un dise\u00f1o para una red de mezcla \"acelerada\" llamada \"cmix\". \"Precomputaci\u00f3n\" se propuso como soluci\u00f3n a la lentitud de las redes de mezcla t\u00edpicas.<\/span><\/p>\n

La precomputaci\u00f3n permite a los nodos mixtos ejecutar la criptograf\u00eda de clave p\u00fablica, que consume mucho tiempo, antes de la fase en tiempo real de tratamiento de mensajes o transmisi\u00f3n de datos entre remitentes y destinatarios. El resultado es un tipo de mixnet muy eficiente que permite a los usuarios enviar y recibir en tiempo real sin comprometer la seguridad ni la privacidad.<\/span><\/p>\n

Parte del proyecto de investigaci\u00f3n inicial fue una implementaci\u00f3n acad\u00e9mica de referencia que sirvi\u00f3 como prueba de concepto para cmix; inclu\u00eda un equipo backend de nodos mixtos y un cliente rudimentario para smartphone.<\/span><\/p>\n

En agosto de 2017, bajo el liderazgo de Chaum, un grupo de desarrollo comenz\u00f3 a crear una implementaci\u00f3n descentralizada, segura y escalable llamada cMixx. El equipo inclu\u00eda a pioneros que desarrollaron los primeros sistemas criptogr\u00e1ficos pr\u00e1cticos, an\u00f3nimos y verificables. Sus miembros fueron de los primeros en proponer y desplegar monedas digitales, redes mixtas, criptograf\u00eda sin permiso, sistemas de votaci\u00f3n verificables y muchos otros avances en criptograf\u00eda.<\/span><\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"
