So this is an academic question I came up with while researching the topic.

Can 802.1X, EAP and RADIUS work together to provide a secure authentication?

If yes, how?

    Yes it can, it's actually quite common setup. It is mostly used in enterprises for example using Windows Server RADIUS. Some info for example here: documentation.meraki.com/MR/Encryption_and_Authentication/…. It's quite difficult and complicated but once setup it works and makes the wifi a lot more secure. Never did it myself but it used to be in one company I used to work for, however it worked only with Windows. – Aria Jul 23 '16 at 20:10

I don't see any reasons why they can't work together, especially when they are different things?

EAP -- Extensible Authentication Protocol. It is just a PROTOCOL which is used by 802.1x authentication server (RADIUS, for example) and client to authenticate each other.

RADIUS -- Remote Authentication Dial-In User Service. It is SERVICE which use one or more authentication protocols used by clients to authenticate themselves. There are several industrial authentication protocols, which include but not limited to: (from less secure to more secure) PAP, SPAP, CHAP, MS-CHAP, MS-CHAPv2, EAP-TLS.
