New Research Challenges for the Security of Ad Hoc and Sensor Networks

In this talk, we provide an overview of the current and upcoming research challenges for the security of ad hoc and sensor networks. We begin with the crucial problem of key establishment; we explain how mobility can be exploited to set up security associations between nodes, and we address the challenges of key setup in sensor networks. We also provide an overview of the security of routing protocols. We explain how two nodes getting in power range of each other can prove this event to a third party at a later stage.

We then address cooperation between wireless nodes, and show that this problem naturally leads to the prevention of greedy behavior in WiFi hot spots; we detail our solution to this problem, called DOMINO. We then address a very novel problem, namely the

secure

location of a node; we explain the potential of this feature, taking the examples of the secure location of smart vehicles in road traffic and the prevention of attacks against sensor networks positions. We show how this feature can be implemented by an appropriate combination of distance bounding and multilateration.
