WEP
Wired Equivalent Privacy (WEP) is an encryption scheme used to secure wireless networks. WEP was
intended to provide comparable confidentiality to a traditional wired network, hence the name. WEP had
many serious weaknesses and hence was superseded by Wi-Fi Protected Access (WPA). Regardless, WEP
still provides a level of security that can deter casual snooping. For more information on configuring WEP for
a target WLAN, see
WEP uses passwords entered manually at both ends (Pre Shared Keys). Using the RC4 encryption algorithm,
WEP originally specified a 40-bit key, but was later boosted to 104 bits. Combined with a 24-bit initialization
vector, WEP is often touted as having a 128-bit key.
