WPA-PSK Authentication process

ruben.montes — Sun, 04 Jul 2021 17:17:45 GMT

Hello,

I'm trying to understand how does WPA-PSK works (without any RADIUS server)... I understand that with WPA the keys are generated dynamically (PMK keys). Who generates them if there are no radius server? How often are they changed?

Thanks,

Ruben

If you use WPA-PSK, you statically configure the PMK. Based on the PMK, the WEP key incrememts one for each packet.

WPA-PSK does not change the PMK.

There is a very useful 10-page security analysis on WPA/WPA2 PSKs at the URL below. Not only does it demonstrate a WPA2 PSK being cracked using the OG150, it discusses the mechanics behind PSKs, the cracking process and more....
