worden. Alle drei haben etwas mit den Sicherheitslücken in Mobiltelefonen mit
Bluetooth Unterstützung zu <span class=SpellE>tun.Diese</span> Vortrag
beschäftigt sich mit genau diesen und ähnlichen Problemen. Es werden die
Mechanismen der <span class=SpellE>Bluetooth-Sicherheit</span> mit Hilfe von
frei verfügbaren Tools und dem offiziellen <span class=SpellE>Linux</span>
Bluetooth <span class=SpellE>Stack</span> <span class=SpellE>BlueZ</span> (<a

um wilde <span class=SpellE>Crypto-Algorithmen</span>, 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 <span class=GramE>der</span> Vortrags erläutert werden. Durch fehlerhafte
Umsetzung oder mangelndem Verständnis entstehen dann die aufgeführten
Sicherheitslücken.<o:p></o:p></span></font></p>
