Il Comitato IETF (Internet Engineering Task Force), impegnato nello sviluppo di protocolli e architetture internet, ha completato la stesura del RFC per il sistema di nomi di dominio GNS (GNU Name System), sviluppato dal progetto GNUnet come un'alternativa completamente decentralizzata e fuori dalla censura al DNS. La specifica, pubblicata come RFC-9498, ha ricevuto lo status di \u00abStandard Proposto\u00bb. L'implementazione di GNS, completamente conforme al RFC pubblicato, \u00e8 parte della piattaforma GNUnet 0.20.0 ed \u00e8 inoltre disponibile nel codice sorgente del progetto GNUnet-Go. <\/p>\n

GNS pu\u00f2 essere utilizzato affianco a DNS e integrato in applicazioni tradizionali, come i browser web. L'integrit\u00e0 e l'immutabilit\u00e0 delle registrazioni sono garantite tramite meccanismi crittografici. A differenza del DNS, in GNS viene utilizzato un grafo diretto al posto di una gerarchia ad albero. server<\/a> viene utilizzato un grafo diretto. La trasformazione dei nomi \u00e8 simile a quella del DNS, ma le richieste e le risposte vengono eseguite mantenendo la riservatezza \u2014 il nodo che elabora la richiesta non sa a chi viene fornita la risposta, e i nodi di transito e gli osservatori esterni non possono decifrare le richieste e le risposte. <\/p>\n

La zona DNS in GNS \u00e8 definita mediante una coppia di chiavi aperte e chiuse ECDSA basate sulla curva ellittica Curve25519. L'uso di Curve25519 \u00e8 considerato da alcuni come una scelta piuttosto strana, poich\u00e9 per ECDSA vengono normalmente utilizzati altri tipi di curve ellittiche, e insieme a Curve25519 viene solitamente impiegato l'algoritmo di firma digitale Ed25519, che \u00e8 pi\u00f9 moderno, pi\u00f9 sicuro e pi\u00f9 veloce rispetto a ECDSA. Dal punto di vista della resistenza crittografica, solleva anche interrogativi la scelta della dimensione della chiave \u2014 32 byte invece dei 64 byte normalmente utilizzati per Ed25519 \u2014 e l'uso della crittografia simmetrica a cascata, che utilizza algoritmi AES e TwoFish in modalit\u00e0 CFB. <\/p>\n

Questo approccio \u00e8 spiegato dalla necessit\u00e0 di implementare chiavi gerarchiche, che consentono di utilizzare la chiave pubblica radice per estrarre la chiave pubblica secondaria, sfruttando la propriet\u00e0 di linearit\u00e0 della curva Curve25519. Questa caratteristica consente di generare chiavi pubbliche secondarie senza la necessit\u00e0 di conoscere le chiavi private radice. Questa tecnica \u00e8 utilizzata anche in Bitcoin. La dimensione della chiave di 32 byte \u00e8 stata scelta per garantire che la chiave possa essere contenuta in una singola entry DNS.
