    Code breakers have discovered a technique for extracting a 104-bit Wired Equivalent Privacy (WEP) key in under a minute.

    Cryptographic weaknesses with the first generation wireless encryption standard have been known for years, but the latest attack requires the capture of just a tenth of the number of packets required by previous approaches. The technique allows for 50 per cent probability of the recovery of a 104-bit WEP key in around a minute (on a 802.11g network running at full speed), and with the capture of 40,000 packets. Doubling the capture period extends the probability of capturing the key to 95 per cent.
