With the ability to use even larger 192-bit and 256-bit keys, if desired, it offers higher security against
brute-force attack than the old 56-bit DES keys. See Figure 26.

The Key Generator button automatically generates a randomized key of the appropriate length. This key is
initially shown in plain text so the user has the opportunity to copy the key. Once the key is applied, the key
is no longer displayed in plain text.

If you are a SOHO user, selecting pre-
shared key means that you don’t have the expense of installing a
Radius Server. Simply input up to 63 character / numeric / hexadecimals in the Passphrase field.
Enable pre-authentication to allow a client to authenticate in advance with the AP before the client is
associated with it. Allowing the AP to pre-authenticate a client decreases the transition time when a client
roams between APs.

roams between APs.
As an alternative, for business applications who have installed Radius Servers, select 802.1x and input the
Primary Radius Server and RFC Backend security settings. Use of Radius Server for key management
and authentication requires that you have installed a separate certification system and each client must
have been issued an authentication certificate.
