comment Why does WPA-PSK not use Diffie-Hellman key exchange?
Michael already suggested a method that provides stronger security: A Diffie-Hellman exchange. This would require an attacker to actively perform a man-in-the-middle-attack, as opposed to starting Wireshark and entering the PSK. I'm also wondering why they didn't implement it like that.

Your're right, that was a typo - I meant random plaintext as input to the asymmetric cipher. I've changed the question accordingly. Thanks!
