Chapter 10: Configuring Security
Static WEP
• The AP must have all keys used by clients for station-to-AP transmit so that
it can de-code the station transmissions.
• The same key must occupy the same slot on all nodes (AP and clients). For
example if the AP defines
abc123 key as WEP key 3, then the client stations
must define that same string as WEP key 3.
• On some wireless client software (like Funk Odyssey), you can configure
multiple WEP keys and define a client station “transfer key index”, and then
set the stations to encrypt the data they transmit using different keys. This
ensures that neighboring APs cannot decode each other’s transmissions.
10.2.4.2 Example Of Using Static WEP
For a simple example, suppose you configure three WEP keys on the access point.
In our example, the Transfer Key Index for the AP is set to 3. This means that the
WEP key in slot “3” is the key the access point will use to encrypt the data it sends.
Figure 10.7 Setting The AP Transfer Key On The Access Point
You must then set all client stations to use WEP and provide each client with one of
the slot/key combinations you defined on the AP.
