WPA(2)-PSK Application Example

A WPA(2)-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

(including spaces and symbols).

2 The AP checks each wireless client's password and (only) allows it to join the

network if the password matches.

3 The AP derives and distributes keys to the wireless clients.

4 The AP and wireless clients use the TKIP or AES encryption process to

encrypt data exchanged between them.

WPA(2)-PSK Authentication

WPA(2) with RADIUS Application Example

You need the IP address of the RADIUS server, its port number (default is

1812), and the RADIUS shared secret. A WPA(2) 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 The RADIUS server distributes a Pairwise Master Key (PMK) key to the AP

that then sets up a key hierarchy and management system, using the pair-

wise key to dynamically generate unique data encryption keys to encrypt

every data packet that is wirelessly communicated between the AP and the

wireless clients.
