Re:Can ARC4 be used properly at all? (Score 1)

The attack is not related to an reused IV. This attack works fine if 40,000 packets have been collected, even if not a single one uses an IV which had been used previously. Some 802.11 stacks use a monotonic counter for IV generation, which will never repead an IV in less than 2^24 packets. Even if such a counter is used, this attack will work perfectly.
