WEP in OPEN SYSTEM is used to protect data not authentication.
One way to detect the correctness of WEP key is to send out several ethernet broadcast with special pattern.
Then, you can check if you receive them or not. If the key is wrong, you will get nothing. If right, AP will broadcast them
and you get them.
You need to do this in driver level or the kernel give you a warning 'duplicate address' and drop them.

OK, Daniel,
so you mean that for the protocol 802.11 even if the set of wep-key on my usb wi-fi key is wrong the answer of iwconfig tells me the MAC of AP where I try to associate?
thanks, Domenico

Unless you are using shared key authentication (and I'd strongly advise
you not to use this), authentication and association can successfully
complete with the wrong WEP key. This is just how 802.11 works.
