Komitet IETF (Internet Engineering Task Force), zajmuj\u0105cy si\u0119 rozwojem protoko\u0142\u00f3w i architektury internetu, zako\u0144czy\u0142 prace nad dokumentem RFC dla systemu nazw domen GNS (GNU Name System), rozwijanego przez projekt GNUnet jako ca\u0142kowicie zdecentralizowan\u0105 i odporn\u0105 na cenzur\u0119 alternatyw\u0119 dla DNS. Specyfikacja, opublikowana jako RFC-9498, otrzyma\u0142a status \u201eProponowanego standardu\u201d. W pe\u0142ni zgodna z opublikowanym RFC implementacja GNS jest cz\u0119\u015bci\u0105 platformy GNUnet 0.20.0 i dodatkowo dost\u0119pna w kodzie \u017ar\u00f3d\u0142owym projektu GNUnet-Go. <\/p>\n

GNS mo\u017ce by\u0107 stosowane r\u00f3wnolegle z DNS i u\u017cywane w tradycyjnych aplikacjach, takich jak przegl\u0105darki internetowe. Integralno\u015b\u0107 i niezmienno\u015b\u0107 rekord\u00f3w zapewnia wykorzystanie mechanizm\u00f3w kryptograficznych. W przeciwie\u0144stwie do DNS w GNS zamiast hierarchii drzewiastej serwer\u00f3w<\/a> zastosowany jest kierunkowy graf. Transformacja nazw jest podobna do DNS, ale zapytania i odpowiedzi s\u0105 realizowane z zachowaniem prywatno\u015bci \u2014 w\u0119ze\u0142 przetwarzaj\u0105cy zapytanie nie wie, do kogo trafia odpowied\u017a, a w\u0119z\u0142y tranzytowe i osoby trzecie nie mog\u0105 odszyfrowa\u0107 zapyta\u0144 i odpowiedzi. <\/p>\n

Strefa DNS w GNS jest definiowana przy pomocy pary kluczy ECDSA na podstawie krzywych eliptycznych Curve25519. U\u017cycie Curve25519 jest postrzegane przez niekt\u00f3rych jako do\u015b\u0107 dziwny krok, poniewa\u017c dla ECDSA stosowane s\u0105 inne typy krzywych eliptycznych, a w parze z Curve25519 zazwyczaj u\u017cywa si\u0119 algorytmu podpis\u00f3w cyfrowych Ed25519, bardziej nowoczesnego, bezpieczniejszego i szybszego ni\u017c ECDSA. Z punktu widzenia odporno\u015bci kryptograficznej, wyb\u00f3r rozmiaru klucza r\u00f3wnie\u017c rodzi w\u0105tpliwo\u015bci \u2014 32 bajty zamiast 64 bajt\u00f3w, kt\u00f3re zwykle s\u0105 stosowane w Ed25519, a tak\u017ce u\u017cycie kaskadowego symetrycznego szyfrowania przy u\u017cyciu algorytm\u00f3w AES i TwoFish w trybie CFB. <\/p>\n

Takie podej\u015bcie wyja\u015bnia konieczno\u015b\u0107 realizacji hierarchicznych kluczy, kt\u00f3re umo\u017cliwiaj\u0105 u\u017cycie klucza publicznego g\u0142\u00f3wnego do uzyskania klucza publicznego potomnego, korzystaj\u0105c z w\u0142a\u015bciwo\u015bci liniowo\u015bci krzywej Curve25519. Ta cecha pozwala na generowanie kluczy publicznych potomnych bez znajomo\u015bci prywatnych kluczy g\u0142\u00f3wnych. Wskazana technika jest r\u00f3wnie\u017c stosowana w Bitcoinie. Rozmiar klucza 32 bajty zosta\u0142 wybrany, aby klucz zmie\u015bci\u0142 si\u0119 w jednym wpisie DNS.
