Before introducing the following authentications, you need to
understand the radius server.
RADIUS server is short for a remote authentication dial-in user
service server, which is most commonly a third party server,
used for authentication of wireless clients who wish to connect
to an access point. The wireless client contacts an access point
(a RADIUS client), which in turn communicates with the
RADIUS server. The RADIUS server performs the
authentication by verifying the client's credentials, to determine
whether the device is authorized to connect to the access
point's LAN. If the RADIUS server accepts the client, it
responds by exchanging data with the access point, including
security keys for subsequent encrypted sessions. A typical
topology which adopt the radius server see figure:
