Wireless Encryption

Wireless Encryption

[Aswin Paranji]

Hi,
I'm trying to encrypt the 802.11 data with my own encryption instead
of WEP or WPA. Can anybody guide me on how to do that and where I need
to change. I'm trying to do this with Raspberry PI 3 device.

Appreciate if you can guide me.

Regards,
Aswin

Umm. You mean you want to do it with the integrated wifi chipset on
RPi3. You can basically forget about that. Encryption is done on the
wifi device. The kernel passes 802.3 packets down to the device so there
is nothing to encrypt at that level and the device/firmware does not
have a way for you to plugin a different encryption.

Arend,

Thanks for the response. What I'm trying to accomplish is to encrypt
the 802.11 data packet that is sent to mac80211 as data frames and
mac80211 sends it to the wifi driver.
I took a look at this blog
"https://www.linux.com/community/blogs/133-general-linux/816721-linux-wireless-networking-a-short-walk"
and thought it would be possible to just encrypt the data part.

I also checked using wireshark where the 80211 data is encrypted using
the wpa key and ssid. I'm looking for a way to encrypt data with out
touching any wifi drivers.

I'am trying to use openwrt to come up with new encryption and see if i
can use it in rapberry pi as a test bed.


Appreciate if you can help.

Regards,
Aswin
