wie BlueBugging, BlueSnarfing und BlueJacking sind durch die Medien publiziert
worden. Alle drei haben etwas mit den Sicherheitslücken in Mobiltelefonen mit
Bluetooth Unterstützung zu tun.Diese Vortrag beschäftigt sich mit genau diesen
und ähnlichen Problemen. Es werden die Mechanismen der Bluetooth-Sicherheit mit
Hilfe von frei verfügbaren Tools und dem offiziellen Linux Bluetooth Stack
BlueZ (<a href="www.bluez.org">www.bluez.org</a>) vorgestellt. Dabei geht es
aber nicht um wilde Crypto-Algorithmen, sondern um die Funktionsweise des
Pairings und das Aktivieren von verschlüsselten Verbindungen. Bluetooth
abstrahiert alle komplexen Vorgänge hinter dem Host Controller Interface (HCI)
und somit auch die Authentifizierung und Verschlüsselung. Dieser Abstraktion
sind natürlich Grenzen auferlegt, die im Laufe der Vortrags erläutert werden.
Durch fehlerhafte Umsetzung oder mangelndem Verständnis entstehen dann die
aufgeführten Sicherheitslücken.<o:p></o:p></span></font></p>

dem eingesetzten Safer+ Algorithmus. Diese Vortrag wählt genau den
entgegengesetzten Weg und betrachtet alles aus der Sicht des Protokoll Stacks
und dessen Anwendungen. <o:p></o:p></span></font></p>
