SIM-Karten von Giesecke & Devrient sind sicher

(PresseBox) (München, )
Die von Giesecke & Devrient kommerziell gelieferten SIM-Karten sind vor dem aktuell in den Medien beschriebenen Angriffsszenario geschützt. Dafür sorgt eine spezielle Implementierung im Betriebssystem der SIM-Karten von G&D. Die SIM-Karten reagieren nicht in der für den Angriff erforderlichen Weise, sondern blocken den Angriff erfolgreich ab.

Karsten Nohl nutzt bei seinem Angriff auf die SIM-Karten eine Schwachstelle beim Einsatz der Verschlüsselungstechnologie Single-DES (Data Encryption Standard): Sendet man an eine so konfigurierte SIM-Karte eine spezielle Steuerungs-SMS vom Netz, überprüft die SIM-Karte zunächst den Berechtigungsschlüssel in dieser Nachricht. Ist dieser Schlüssel falsch oder nicht vorhanden, gibt es verschiedene Antwort-Szenarien.
