11 I'm glad you can now connect! :-)
13 CCMP which stands for "Counter Mode with Cipher Block Chaining Message
14 Authentication Code Protocol" uses the Counter Mode with CBC-MAC, which from
15 what I understand uses 128bit AES ciphers. So, as long as you set up
16 wpa_supplicant to use proto=RSN with pairwise=CCMP and group=CCMP you will
17 always connect with the AES encryption standard.
19 NOTE: It is not necessary to specify CCMP because it is used by default as
20 the first option, but if you don't specify it and the AP uses WPA/TKIP only,
21 then instead of the connection failing wpa_supplicant will switch from CCMP to
22 TKIP. I'm stating the obvious here, but if having a wireless connection is
23 more important than *always* using AES, then of course you do not need to
24 specify CCMP.
