Don't use WEP, say German security researchers

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.

WEP is a protocol for securing wireless LANs. WEP stands for "Wired Equivalent Privacy" which means it should provide the level of protection a wired LAN has. WEP therefore uses the RC4 stream to encrypt data which is transmitted over the air, using usually a single secret key (called the root key or WEP key) of a length of 40 or 104 bit.
