I am reading about the WPA2 protocol. The authentication step uses 802.1X protocol which in turn uses the EAP framework; in which a so called 'EAP method' does the authentication (diagram from book).
The WPA2 certification requires the following EAP methods implemented (source):
- EAP-TLS
- EAP-TTL
- PEAPv0/EAP-MSCHAPv2
- PEAPv1/EAP-GTC
- EAP-SIM
Let's say I unwrap my consumer AP, set it for WPA2, manually enters the passphrase (PSK) in both STA and AP.
How does the authentication happen? By authentication, I simply mean that both parties prove that they know the key (without revealing the key). Does that happen with the 802.1X and EAP framework (as shown in the diagram), and in that case which EAP method handles this?
Or is 802.1x not used? Or is 802.1x used, but not the EAP framework?
