Abstract :

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.
