1.2.5.1 Encryption and Authentication
The switch can implement the following encryption and authentication types:
• WEP
• WPA
• WPA2
• Keyguard-WEP
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was superseded by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 Configuring WEP 64 on page 4-53 or
Configuring WEP 128 / KeyGuard on page 4-54 .
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.
