802.1x, EAP, eduroam and anonymous identity

When you authenticate with eduroam, your credentials, that is your username and your password, must be sent by your computer to a server at CSIM.

Your password is always encrypted, so it is not a problem.

But your username is not. The system needs to know the part in order to roam the authentication to CSIM server. If the system can see the part, it can also see your username. This is not a threat as big as knowing your password, but that could allow phishing, social engeeniring and open the gate to some attacks. To mitigate this risk, an anonymous identity can be used while negociating to roaming to CSIM server. Once this roaming is established, an encrypted tunnel is opened and your real username is sent encryoted.

This page describes 802.1x and EAP and how it applies to eduroam in greater details.
