3. If mutual authentication is successful, the client and RADIUS
server derive a dynamic, session-based WEP key that is unique
to the client.
4. The RADIUS server transmits the key to the access point using a
secure channel on the wired LAN.
5. For the length of a session, or time period, the access point and
the client use this key to encrypt or decrypt all unicast packets
that travel between them.
Refer to the “Using LEAP” section on page 5-21 for instructions on
enabling or disabling LEAP and entering the LEAP username and
password.
Additional WEP Key Security Features
Client adapter firmware version 4.25.23 and greater and Windows CE
driver version 2.2x and greater support three new security features
designed to prevent sophisticated attacks on your wireless network’s
WEP keys. These features (MIC, TKIP, and broadcast key rotation) do
not need to be enabled on the client adapter; they are supported
automatically in the driver and firmware versions listed above.
However, they must be enabled on the access point.

required to enable these security features. Refer to
the Cisco Aironet Access Point Software
Configuration Guide for instructions on enabling
these security features on the access point.
