Game Theory and Wireless Security

Securing wireless networks is notoriously a huge challenge. In this talk, we will first describe current trends in wireless technology and upcoming wireless networks, such as sensor, vehicular, mesh, and RFID networks. We will then address their vulnerabilities and the existing or envisioned protection techniques.
We will then consider the specific example of ephemeral networks, namely networks in which the interactions between nodes are short- lived, typically due to their mobility. We will focus on the fundamental security operation of revocation in such networks. We will show how game theory can be used to model the different possible revocation strategies of the nodes and discuss the implications of this model on the protocol design.
