Just a warning about the "secure" plugin. The only thing it does it to use a
shared secret to calculate a hash value and put it into each packet (plus a
timestamp against replay attacks). You can get more security by just
encrypting your Layer 2 with a symmetric key (not WEP because it's broken).
I think that WPA supplicant should support some static shared key for WPA(2)
in linux, but I'm not sure.
