eduroam (EDUcation ROAMing) is a world-wide community whose aim is to "open your laptop and be online". eduroam allows users (researchers, teachers, students, staff) from participating institutions to securely access the Internet from any eduroam-enabled institution. The eduroam principle is based on the fact that the users' authentication is done by the user's home institution, whereas the authorisation decision allowing access to the network resources is done by the visited network. Put simply, a University of West London user can visit other eduroam institutions and log into their network using their University of West London username and password.
eduroam uses 802.1X to authenticate users. To enable authentication at any eduroam site, a world-wide hierarchical infrastructure of authentication servers (RADIUS) exists which securely tunnel users' authentication attempts back to their home institution. The current status of this infrastructure can be viewed live.
In the UK, eduroam is operated and provided by the JISC. All UK eduroam sites are members of the JISC organisation and must comply with the eduroam UK Technical Specification.
The eduroam UK service runs across the JISC network known as JANET (Joint Academic NETwork) which provides our gateway to the Internet. The eduroam UK Service manages the UK authentication infrastructure which connects to the European eduroam infrastructure.
