4.3.4.1 WPA-PSK Application Example
A WPA-PSK application looks as follows.
1
First enter identical passwords into the AP and all wireless clients. The Pre-Shared
Key (PSK) must consist of between 8 and 63 ASCII characters or 64 hexadecimal
characters (including spaces and symbols).
2
The AP checks each wireless client's password and allows it to join the network
only if the password matches.
3
The AP and wireless clients generate a common PMK (Pairwise Master Key). The
key itself is not sent over the network, but is derived from the PSK and the SSID.
4
The AP and wireless clients use the TKIP or AES encryption process, the PMK and
information exchanged in a handshake to create temporal encryption keys. They
use these keys to encrypt data exchanged between them.

WPA-PSK Authentication
4.3.4.2 WPA with RADIUS Application Example
To set up WPA, you need the IP address of the RADIUS server, its port number
(default is 1812), and the RADIUS shared secret. A WPA application example with
an external RADIUS server looks as follows. "A" is the RADIUS server. "DS" is the
distribution system.
1
The AP passes the wireless client's authentication request to the RADIUS server.
2
The RADIUS server then checks the user's identification against its database and
grants or denies network access accordingly.
3
A 256-bit Pairwise Master Key (PMK) is derived from the authentication process by
the RADIUS server and the client.
