"As it turns out, the US Department of Energy (and almost everyone else except members of Congress) was correct when they predicted that there would be little energy savings. This echoed concerns voiced after a similar experiment was attempted in Australia. Critics pointed out a basic fact: the gains in the morning will be offset by the losses at night, and vice-versa, at both ends of the switch. That appears to be exactly what happened.""
Like the older attacks on WEP this attack uses sniffed IVs in order to break/compute/crack the WEP key. The nice thing about this attack is that it only needs between 40.000 and 85.000 unique IVs (older attacks needed between 250.000 and 1.000.000 in order to succeed). This all ready reduces the overall attack time since one needs to capture less packages. But the attack also uses a new/other attack on RC4 that further improves the speed. The paper gives an average of 3 seconds (crack time) on 1.7Ghz Pentium-M. The attack even works with 5000 keys so it should be usable on a PDA or SmartPhone.

Fun fact from the article:
The brass of one of the detectors is originating from old Russian shell casings."
