Die als RFC-9498 ver\u00f6ffentlichte Spezifikation erhielt den Status 'Entwurf eines Standards'. Eine vollst\u00e4ndig konforme Implementierung von GNS ist in der Plattform GNUnet 0.20.0 enthalten und zus\u00e4tzlich im Quellcode des Projekts GNUnet-Go verf\u00fcgbar.           <\/p>\n<p>GNS kann parallel zu DNS eingesetzt werden und in traditionellen Anwendungen wie Webbrowsern verwendet werden. Die Integrit\u00e4t und Unver\u00e4nderbarkeit der Eintr\u00e4ge wird durch den Einsatz kryptografischer Mechanismen gew\u00e4hrleistet. Im Gegensatz zu DNS verwendet GNS anstelle einer baumartigen Hierarchie <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/de\/server\/\"   title=\"Server\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"1648\">Server<\/a> Es wird ein gerichteter Graph verwendet. Die Namensumwandlung \u00e4hnelt DNS, jedoch werden Anfragen und Antworten unter Wahrung der Privatsph\u00e4re ausgef\u00fchrt \u2013 der verarbeitende Knoten wei\u00df nicht, wem die Antwort gegeben wird, und Transitknoten sowie externe Beobachter k\u00f6nnen Anfragen und Antworten nicht entschl\u00fcsseln.    <\/p>\n<p>Eine DNS-Zone in GNS wird durch ein Schl\u00fcsselpaar aus \u00f6ffentlichem und privatem ECDSA-Schl\u00fcssel auf Basis der elliptischen Kurven Curve25519 definiert. Die Verwendung von Curve25519 wird von einigen als recht seltsamer Schritt angesehen, da f\u00fcr ECDSA normalerweise andere Arten elliptischer Kurven verwendet werden, und in Kombination mit Curve25519 h\u00e4ufig der modernere und sicherere Algorithmus Ed25519 f\u00fcr digitale Signaturen eingesetzt wird, der zudem schneller ist als ECDSA. Auch die Wahl der Schl\u00fcsselgr\u00f6\u00dfe \u2013 32 Bytes anstelle von 64 Bytes, die normalerweise f\u00fcr Ed25519 verwendet werden \u2013 und die Anwendung von kaskadierter symmetrischer Verschl\u00fcsselung mit den Algorithmen AES und TwoFish im CFB-Modus werfen aus kryptographischer Sicht Fragen auf.    <\/p>\n<p>Ein solcher Ansatz wird durch die Notwendigkeit gerechtfertigt, hierarchische Schl\u00fcssel zu implementieren, die es erm\u00f6glichen, den Stamm\u00f6ffentlichen Schl\u00fcssel zur Ableitung untergeordneter \u00f6ffentlicher Schl\u00fcssel zu verwenden, wobei die Linearit\u00e4t der Curve25519 ausgenutzt wird. Diese Besonderheit erm\u00f6glicht es, untergeordnete \u00f6ffentliche Schl\u00fcssel ohne Kenntnis der privaten Stamm-Keys zu generieren. Diese Technik wird auch in Bitcoin verwendet. Die Gr\u00f6\u00dfe des Schl\u00fcssels von 32 Bytes wurde gew\u00e4hlt, damit der Schl\u00fcssel in einen DNS-Eintrag passt.<br \/>\n<br \/>Quelle: <a content=\"nofollow\" rel=\"nofollow\"
