The available encryption methods also depend on the authentication method used. Kerberos authentication
supports only the WEP 128 (104 bit key)

5.3.5 Configuring WEP Encryption

Wired Equivalent Privacy (WEP) is a security protocol specified in the IEEE Wireless Fidelity (Wi-Fi) standard,
802.11b. WEP is designed to provide a WLAN with a level of security and privacy comparable to that of a
wired LAN. WEP might be all that a small-business user needs for the simple encryption of wireless data.
However, networks that require more security are at risk from a WEP flaw. The existing 802.11 standard
alone offers administrators no effective method to update keys. Key changes require the manual re-
configuration of each Access Port. An unauthorized person with a sniffing tool can monitor a network for less
than a day and decode its encrypted messages.
WEP is available in two encryption modes: 40 bit (also called 64-bit) and 104 bit (also called 128 bit). The
104-bit encryption mode provides a longer algorithm that takes longer to decode than that of the 40-bit
encryption mode.
NOTE: The WEP 128 encryption mode allows devices using 104-bit key and devices using 40-bit keys to
talk to each other using 40-bit keys, if the 104-bit devices permit this option.

WLAN to have a different key.

5.3.6 Configuring WPA/WPA2-TKIP Encryption

Wi-Fi Protected Access (WPA) is specified in the IEEE Wireless Fidelity (Wi-Fi) standard, 802.11i. This
security standard provides more sophisticated data encryption than WEP. WPA is designed for corporate
