Hello,

Thank you for posting here.

The Wired Equivalent Privacy (WEP) encryption in 802.11b standard provides
the secure wireless network access. WPA-PSK is a special mode of WPA users
without an enterprise authentication server and provides the same strong
encryption protection. You can configure WPA-PSK for the Router or Access
Point. Users that can provide the secure key will be able to access the
network. The option "key is provided Automatically" can be chosen for
network that AP router is set to dynamically provide network key for
clients. A network security key or passphrase can help protect your
wireless network from this type of unauthorized access.

For IAS server and the AP (remote access server), there is a shared secret
which is a text string that serves as a password between a RADIUS client
(AP) and RADIUS server (IAS server). You need to match the shared secret
between IAS server and AP for the proper authentication and authorization.
Shared secrets are used to verify that RADIUS messages, with the exception
of the Access-Request message, are sent by a RADIUS-enabled device that is
configured with the same shared secret. Shared secrets also verify that the
RADIUS message has not been modified in transit (message integrity). The
shared secret is also used to encrypt some RADIUS attributes, such as
User-Password and Tunnel-Password.
