Simultaneous Authentication of Equals (SAE) is a Diffie-Hellman based key establishment protocol. It is part of the 802.11s standard for mesh networking, but can also be used in AP mode. Like WPA-PSK it works with a pre-shared password, but in contrast to WPA-PSK it protects against dictionary attacks (c.f. <>).

Due to this security benefit, I suggest enabling the CONFIG_SAE build option.

Sorry, should clarify this: it protects against _offline_ dictionary attacks

I'm a bit confused now - even though you closed this with "fixed", the option is not enabled in the wpa_supplicant packages.

I suggest to add CONFIG_MESH=y too to support 802.11s.

Popular FritzBoxes support WPA3 now in their Beta-firmware, but as I tried to use it: invalid key_mgmt 'SAE'. Any reason why this option is still disabled?

I have a wpa_supplicant build copying a bunch of CONFIG enables from Ubuntu and Fedora; pending tests.
