Eduroam

eduroam is short for Education Roaming. By using 802.1x security standards over RADIUS-based infrastructure, eduroam aims the users of member institutions to use the network without any problems in other educational institutions.
Users of eduroam member institutions can connect to the network from another eduroam member institution (Guest Institution) with the username and password they use to connect to the network in their own institution (Home Institution). When the user sends a connection request to the eduroam broadcast he received while at the guest institution, the authorization server of the guest institution determines whether the user is authorized by directing that user to the authorization server of the user home institution. The fact that all these queries are made through an encrypted tunnel created between the servers prevents the username and password pairs from being seen outside of the user’s own home server. In this case, the only thing users must do is to define the eduroam wireless network in the institution they host as if they are connected to their own institution’s network.
eduroam has a federation hierarchy. Currently, there are two confederations in the world: the European eduroam confederation and the Asia-Pacific (APAN) eduroam confederation. eduroam member institutions send inquiries to the eduroam federations in their own countries, and the federations of the countries send inquiries to the confederations they are affiliated with. Thanks to this hierarchy, every new federation that joins the European eduroam confederation and the APAN confederation to which Turkey is affiliated, and every new institution that joins them, can be recognized by everyone involved. You can visit the eduroam page to see the participants in the confederations.
