Kaltstart Angriff auf verschlüsselte Systeme

Eine Schwachstelle gängiger Verschlüsselungssoftware stellt der Arbeitsspeicher eines Rechners dar. Viele Anwendungen zur Verschlüsselung legen Schlüssel für den Zugriff auf die Daten im Arbeitsspeicher des Rechners ab. Gelingt es einem Angreifer ein Speicherabbild des Arbeitsspeichers anzufertigen, lässt sich darin der Schlüssel ausfindig machen.

Um an den Inhalt des Arbeitsspeichers zu gelangen demonstrierte die Princeton University im Frühjahr 2008 einen sogenannten Kaltstart-Angriff. Dabei machten man sich den Effekt zu nutze, dass der Arbeitsspeicher seinen Inhalt nach dem Abschalten des Rechners nicht sofort verliert, sondern erst nach einer kurze Zeitspanne. Unter Zuhilfenahme von Kühlmitteln lässt sich diese Zeitspanne offenbar bis zu mehreren Stunden ausdehnen.

Ausführliche Information über den Kaltstart Angriff finden sich bei heise.de und auf den dort verlinkten Seiten.
