Figure 10.3 Providing A Wireless Client With A WEP Key
If you have a second client station, that station also needs to have one of the WEP keys
defined on the AP. You could give it the same WEP key you gave to the first station. Or for
a more secure solution, you could give the second station a different WEP key (key 2, for
example) so that the two stations cannot decrypt each other’s transmissions.
Static WEP With Transfer Key Indexes On Client Stations
Some Wireless client software (like Funk Odyssey) lets you configure multiple WEP keys
and set a transfer index on the client station, then you can specify different keys to be used
for station-to-AP transmissions. (The standard Windows wireless client software does not
allow you to do this.)
To build on our example, using Funk Odyssey client software you could give each of the
clients WEP key 3 so that they can decode the AP transmissions with that key and also give
client 1 WEP key 1 and set this as its transfer key. You could then give client 2 WEP key 2
and set this as its transfer key index.
Figure 10.2.2.3 illustrates the dynamics of the AP and two client stations using multiple
WEP keys and a transfer key index.
