In this case all the wireless clients are loaded
with the secret key information. The same key
is loaded into the access point.
The advantage of this approach is that it is
simple to manage, since there is only one key
active at a given time (chosen from an
available 'pool' of up to four keys). You can
change the key on a regular basis without
disrupting the network (see Using shared WEP
keys on page 136).
The disadvantage of a shared WEP key is that if
it is known by a number of people there is a
greater chance of it being disclosed outside the
organization. Every time someone leaves the
group it may be necessary to change the shared
WEP key to maintain security.
Personal WEP keys
When using personal WEP keys:
• Each wireless client is assigned a personal
WEP key
• A list of personal WEP keys is held by the
access point, or is accessible via an external
database (see Key databases on page 140).
• An access point uses a different key for
each client which is being addressed. This
provides a high level of security.
In a large organization it may be more
convenient to use this method. If someone
leaves the company, or if a laptop is stolen for
example, you only need to remove or change
one key in the database.
