Wi-Fi Protected Access 2 - Pre-Shared Key (also called WPA or WPA2 Personal) is a method of securing your network using WPA2 with the use of the optional Pre-Shared Key (PSK) authentication, which was designed for home users without an enterprise authentication server.

To encrypt a network with WPA2-PSK you provide your router with a plain-English passphrase between 8 and 63 characters long, instead of an encryption key. Using a technology called Temporal Key Integrity Protocol, that passphrase - along with the network SSID - is used to generate unique encryption keys for each wireless client. Those encryption keys are constantly changed.

Why does WPA-PSK not use Diffie-Hellman key exchange?

Is there a reason, why in pre-shared key mode, Wi-Fi session key is not secured with something like Diffie-Hellman but instead is derived from PSK key and some information exchanged in clear during sign-on?

Encoding information in packet lengths to actively sidestep encryption

If you've only got an encrypted data channel can you actively sidestep the encryption and communicate with an outside party who can see the data but cannot decrypt it? Yes - if you can find some leaky aspect in the process that's still visible after…

Is WPA2(PKS) AES vulnerable to 4 way hand shake and brute force attack?

I can easily crack a WPA TKIP using a dictionary/brute force method, provided that I collect the four way handshake. Is the same method possible on WPA2 AES? I cannot find any articles about '4 way handshake capture' and 'WPA2 AES cracking'…

What is the exact algorithm and functions of the 4 way handshake?

I have to make a detailed diagram of the 4 way handshake and formulas for its functions so I need to know the exact process behind it. Like precisely what functions are used in it? I have been trying to search this for days but all I can find is…
