Hostap configuration - internet resoucres ?

[Andreas Jellinghaus]

two machines? create a wep key, enter it on both sides, use
an ad hoc net, the world is fine.

note: wep is not secure.

does anyone know:
can I use CCMP/AES in a static configuration? 
i.e. use some ad-hoc net with a static configured
shared secret? will that be secure, or is some
key changing protocol required for real security?

thanks for your help.
