Abstract:
Many organizations, from universities to corporate networks or hotspot providers, have deployed WiFi networks permitting external users to connect to the Internet through their networks. Such WiFi roaming has many security repercussions, for the visited network as well as for the visiting user.

In this presentation, we first describe some risks of sharing WiFi networks and discuss the drawbacks of the existing roaming solutions. Then, we explain how the tunnel-based solution being developed within the ALAWN project resolves these problems and provides a secure method to share WiFi networks. We discuss our experience in developing a first prototype within the hostap open-source implementation.

This is joint work with researchers from the crypto group of Université catholique de Louvain and researchers from CRID or Facultés Universitaires Notre-Dame de la Paix. This work is funded by DGTRE within the ALAWN project.
