El Comit\u00e9 IETF (Internet Engineering Task Force), encargado del desarrollo de protocolos y la arquitectura de Internet, ha completado la elaboraci\u00f3n del RFC para el sistema de nombres de dominio GNS (GNU Name System), desarrollado por el proyecto GNUnet como una alternativa completamente descentralizada y no sujeta a censura al DNS. La especificaci\u00f3n, publicada como RFC-9498, ha obtenido el estatus de \u00abPropuesto como est\u00e1ndar\u00bb. La implementaci\u00f3n del GNS, completamente conforme al RFC publicado, forma parte de la plataforma GNUnet 0.20.0 y est\u00e1 adicionalmente disponible en la base de c\u00f3digo del proyecto GNUnet-Go. <\/p>\n

GNS puede utilizarse junto al DNS y en aplicaciones tradicionales, como navegadores web. La integridad e inalterabilidad de los registros se garantiza mediante el uso de mecanismos criptogr\u00e1ficos. A diferencia del DNS, GNS utiliza un gr\u00e1fico dirigido en lugar de una jerarqu\u00eda en \u00e1rbol. servidores<\/a> se aplica un gr\u00e1fico dirigido. La transformaci\u00f3n de nombres es similar al DNS, pero las solicitudes y respuestas se realizan con un enfoque en la privacidad: el nodo que procesa la solicitud no sabe a qui\u00e9n se entrega la respuesta, y los nodos de tr\u00e1nsito y observadores externos no pueden descifrar las solicitudes y respuestas. <\/p>\n

La zona DNS en GNS se define utilizando un par de claves p\u00fablicas y privadas ECDSA basadas en la curva el\u00edptica Curve25519. El uso de Curve25519 es considerado por algunos como un paso bastante extra\u00f1o, ya que otros tipos de curvas el\u00edpticas son com\u00fanmente empleadas para ECDSA, y generalmente el algoritmo de firma digital Ed25519, que es m\u00e1s moderno, m\u00e1s seguro y m\u00e1s r\u00e1pido que ECDSA, se utiliza junto con Curve25519. Desde la perspectiva de la resistencia criptogr\u00e1fica, tambi\u00e9n genera dudas la elecci\u00f3n del tama\u00f1o de la clave: 32 bytes en lugar de los 64 bytes que normalmente se utilizan para Ed25519, as\u00ed como la implementaci\u00f3n de cifrado sim\u00e9trico en cascada, utilizando los algoritmos AES y TwoFish en modo CFB. <\/p>\n

Este enfoque se explica por la necesidad de implementar claves jer\u00e1rquicas, que permiten utilizar la clave p\u00fablica ra\u00edz para extraer la clave p\u00fablica hija, aprovechando la propiedad de linealidad de la curva Curve25519. Esta caracter\u00edstica permite generar claves p\u00fablicas hijas sin necesidad de conocer las claves privadas ra\u00edz. Esta t\u00e9cnica tambi\u00e9n se utiliza en Bitcoin. El tama\u00f1o de la clave de 32 bytes se eligi\u00f3 para que quepa en un solo registro DNS.
