PPSK and 6GHz

[JA]

Hi

I was reading in the latest version of the XIQ User Guide and it stated

"Private Pre-Shared Key requires users to authenticate by entering a PPSK unique to each user (not available for 6 GHz)."

Does anyone know if use in 6GHz something that may be added later?

Thanks

Thank you Jan.

I wonder if there is a replacement in the works for something similar that will work with WPA3?

Thanks again.

PPSK in WPA2 Personal can be implemented by the AP in two ways:

1. based on the client device MAC address - fails with MAC address randomization
2. based on the individual PSK that the client uses in the 4-way handshake to derive the encryption keys - does not work in WPA3 Personal

The only way I see for this to work in 6GHz is some proprietary implementation of WPA2 Personal outside of the IEEE 802.11ax standard and of the Wi-Fi Alliance certifications. One may question if this is worth the trouble.

WPA3 is mandatory in 6GHz, no other method (e.g.WPA, WPA2,WEP) is allowed.

PPSK relies on WPA2 Personal, because WPA2 P. allows the reverse-engineering of the passphrase based on it contributing to the master session key. WPA3 does not allow that.
