When I try connecting to wireless networks (with no RADIUS server), I enter the password and it goes through an authentication process. After the station successfully connects to the access point, a 4-way handshake is done to generate PTK, GMK to encrypt the traffic.
In this case, I want to know how the authentication is done. I wonder if there are some protocols in wireless network authentication (generally in home networks, preshared-key settings).
I'm not talking about the 4-way handshake. Though I searched for WPA-PSK authentication, all I could find were posts explaining the 4-way handshake. In this post https://www.wifi-professionals.com/2019/01/4-way-handshake, I want to know what is going on in the authentication management frames. This is the image in the post what I am curious about.
