Fraunhofer-Forscherteam zeigt, wie sich falsche Webzertifikate ausstellen lassen

(PresseBox) (Sankt Augustin, )
Ein Forscherteam des Fraunhofer-Instituts für Sichere Informationstechnologie SIT in Darmstadt hat eine Möglichkeit gefunden, betrügerische Website-Zertifikate auszustellen. Diese Zertifikate sollen die Vertrauenswürdigkeit von Internet-Domains sicherstellen. Das Team um Dr. Haya Shulman hat gezeigt, dass eine Schwachstelle in der Domänenvalidierung ausgenutzt werden kann und deshalb die Sicherheit von Internet-Infrastrukturen verbessert werden muss. Die Forscher haben betroffene Web-CAs (Zertifikats-Ausgabestellen) informiert und stellen eine Implementierung vor, die Web-CAs verwenden können, um den Angriff abzuschwächen. Weitere Informationen unter www.sit.fraunhofer.de/dvpp .

Webzertifikate sind die Grundlage des SSL-/TLS-Protokolls, das die meisten Websites schützt, wie beispielsweise Mailanbieter und geschäftliche Anwendungen, Online-Handelsplattformen und Online-Banking.
