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.
