What will happen if a WEP authentication challenge string is reused? If the access point ran out of unique random numbers and reused one then what would happen? I'd think that if challenges were reused then an eavesdropper could intercept the challenge and the response, store them, and wait for the challenge to be used again to use the stolen response. Then the attacker could connect without the WEP key. However, since there's a flaw that allows for an attacker intercept a challenge and response pair and connect without knowing the WEP key, then is it really so bad if a challenge repeats? Would it be insecure to use the same challenge over and over again?
