Don’t use WEP for Wireless Encryption
April 4th, 2007
On the off chance you haven’t got the message yet and switched your WiFi connection to WPA:
“…it is possible to recover a 104 bit WEP key with probability 50% using just 40,000 captured packets… for 85,000 data packets [the success probability is] about 95%… 40,000 packets can be captured in less than one minute under good condition. The actual computation takes about 3 seconds and 3 MB main memory on a Pentium-M 1.7 GHz…”
OK kids? WEP is bad.

Hah, we just dicussed this in a lecture this week. Most of the people in class were oblivious, but some nerd at the front whipped out his laptop and started to airsnort. Or something like that.
