And then the different types of authentication mechanisms.
Open system authentication means you just
need to know the network name and that's it, you're in.
So a shared key authentication means you need to know a password.
Shared key like a web key or WPA, pre shared key.
Wifi authentication process using a centralized server, this is radius.
All right, so again, that's 802.1 X authentication.
I just want to put the dot between the one and the X.
It's 802.1 X, which is actually port
security, but that allows for connection request to be sent to a radius server.
The access point becomes the radius client.
This sometimes generates a little
confusion and then the client connects the access point.
Actually, I have two clients in the
process, client to client, client to server, authentication request.
Now in a diameter configuration, which we talked a little bit briefly about in our
triple A discussion, a diameter server will actually give you a peer to peer.
They can challenge back and forth, but you
just don't really see any diameter out there.
So it's probably going to be radius.
