Synopsis

With the wide proliferation of wireless devices, securing information
sent over the wireless medium becomes vital. The wireless setting,
however, introduces a number of challenges and limitations that cannot
be fully resolved using traditional security solutions. These challenges
mainly originate from the open and broadcast nature of the wireless
communication medium and from mobility aspects.

In this talk, I address this problem and propose different solutions
tailored to secure wireless communication scenarios. I focus on the
vulnerabilities to a range of communication interference attacks in
which attackers interfere with the communication in order to prevent the
reception of the correct, timely information transmitted by the sender.
In particular, my talk covers the following aspects: (i) the
vulnerability of wireless radio transmissions to signal-layer attacks,
(ii) spoofing attacks against satellite navigation systems (like GPS),
and (iii) novel techniques for enabling communication under jamming
attacks without shared secrets.
