IETF (Internet Engineering Task Force) on, mis tegeleb interneti protokollide ja arhitektuuri arendamisega, on l\u00f5petanud GNS (GNU Name System) domeeninime s\u00fcsteemi jaoks RFC koostamise, mida arendab GNUnet projekt, et pakkuda t\u00e4ielikult detsentraliseeritud ja tsensuurile allumatut DNS-i alternatiivi. Spetsifikatsioon, mis avaldati RFC-9498 all, sai \u201eEhitamise ettepaneku\u201d staatuse. RFC-le t\u00e4ielikult vastav GNS rakendus on osa GNUnet 0.20.0 platvormist ja on samuti saadaval GNUnet-Go projekti koodibaasis. <\/p>\n

GNS-i saab kasutada koos DNS-iga ja traditsioonilistes rakendustes, nagu veebibrauserid. Kirjete terviklikkus ja muutumatuse tagamine toimub kr\u00fcptograafiliste mehhanismide abil. Erinevalt DNS-ist kasutab GNS puustruktuuri asemel orienteeritud graafi. Nimekonversioon on sarnane DNS-iga, kuid p\u00e4ringute ja vastuste t\u00f6\u00f6tlemise k\u00e4igus s\u00e4ilitatakse privaatsus \u2014 p\u00e4ringu t\u00f6\u00f6tlev s\u00f5lm ei tea, kellele vastus antakse, ja juhuslikud s\u00f5lmed ning kolmandad osalised ei saa p\u00e4ringuid ja vastuseid dekodeerida. serverite<\/a> Kasutatakse suunatud graafikut. Nimedekonverteerimine sarnaneb DNS-iga, kuid p\u00e4ringud ja vastused toimuvad privaatsust s\u00e4ilitades \u2014 p\u00e4ringu t\u00f6\u00f6tlev s\u00f5lm ei tea, kellele vastus antakse, ja edastus\u00f5lmed ning kolmandad isikud ei saa p\u00e4ringuid ja vastuseid dekr\u00fcpteerida. <\/p>\n

GNS DNS-ala m\u00e4\u00e4ratakse ECDSA avatud ja suletud v\u00f5tmete paariga, mida toetavad Curve25519 elliptilised k\u00f5verad. Curve25519 kasutamine on paljude arvates \u00fcsna kummaline samm, kuna ECDSA jaoks kasutatakse muid t\u00fc\u00fcpe elliptilisi k\u00f5veraid, ja koos Curve25519 kasutatakse tavaliselt Ed25519 digitaalsete allkirjade algoritmi, mis on kaasaegsem, turvalisem ja kiirem kui ECDSA. Kr\u00fcptograafilise tugevuse seisukohalt toob samuti k\u00fcsimusi v\u00f5tme suuruse valik \u2014 32 baiti asemel 64 baiti, mida tavaliselt kasutatakse Ed25519 puhul, samuti kaskaadse s\u00fcmmeetrilise \u0161ifreerimise rakendamine, kasutades AES ja TwoFish algoritme CFB re\u017eiimis. <\/p>\n

Taolise l\u00e4henemise selgitab hierarhiliste v\u00f5tmete rakendamise vajadus, mis v\u00f5imaldab kasutada juure avatud v\u00f5tme kaudu alumise taseme avatud v\u00f5tme leidmiseks, kasutades Curve25519 k\u00f5vera lineaarsust. See omadus v\u00f5imaldab saada alumise taseme avatud v\u00f5tmeid, teadmata juure suletud v\u00f5tmeid. Antud tehnika on samuti kasutusel Bitcoinis. 32-bittine v\u00f5tme suurus on valitud nii, et see mahuks \u00fchte DNS-i kirje.
