Don't use WEP for Wi-Fi security, researchers say

"April 04, 2007 (IDG News Service) -- The Wi-Fi security protocol WEP should not be relied on to protect sensitive material, according to three German security researchers who have discovered a faster way to crack it. They plan to demonstrate their findings at a security conference in Hamburg this weekend.

Now it takes just three seconds to extract a 104-bit WEP key from intercepted data using a 1.7-GHz Pentium M processor. The necessary data can be captured in less than a minute, and the attack requires so much less computing power than previous attacks that it could even be performed in real time by someone walking through an office."
