Does CYW4356 support WPA3?

[akckwang]

Hi,
We're evaluating AW-CM217NF for wlan+bt module for a project,
the module integrated CYW4356,

Since WFA(Wi-Fi Alliance) announced WPA3 is mandatory item for Wi-Fi CERTIFICATED certification,
so we do like to consult whether the CYW4356 support WPA3?

Here is a pdf file, the page 22 mentioned CYW4356 supports WPA3,
https://www.iothingsweek.com/wp-content/uploads/2021/05/Bottura.pdf

But as other Cypress document, seems CYW4356 only support WPA/2 only?

Thanks~

Hi @akckwang ,

The 4356 supports WPA3 only via the external supplicant. The in driver supplicant does not support it.

Features like wpa3 could be added via software updates that might have not been present when the original datasheet was made. So it will be included in future revisions.

Thank You,

Hi @raks_99 ,

Could you describe more detailed for the "external supplicant"?
is't wpa_supplicant what we usually using on Linux?

Isn't 4356 supporting WPA3 yet for now?

Thanks~

Hi @akckwang ,

Our devices have a feature known as in driver supplicant. This is a lightweight supplicant which eliminates the need for any external supplicant on the host device.

Currently, with the latest version of the firmware for 4356, we support WPA3 via external supplicant. (by setting CONFIG_SAE=y in .config)

Thanks

Hello:

    from the last reply,  wpa3 should be supported already on the firmware side, better to get further support from your local Infineon support team to get the whole patch for a test.
