The number of mobile devices within academia has increased significantly over the last couple of years and users expect to be able to get connectivity everywhere, at home, on the road and at educational institutions. At the same time however, the security of wireless LANs becomes more and more of a concern In 2003, the TERENA Task Force on Mobility  was created to look at WLAN security issues and to formulate requirements to design an international roaming solution that would provide National Research and Educational Networks’ (NRENs’) users with secure Internet access at academic campuses across Europe. The solution proposed was tested and proved to be very successful with more and more institutions joining it. This infrastructure is called eduroam, which stands for Education Roaming. Within the 6th framework project GÉANT2 , the aim is to expand the existing infrastructure into a pan-European full service for Roaming and Authentication/Authorisation.
