6.5 Introduction to WPA
Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. WPA is preferred to
WEP as WPA has user authentication and improved data encryption. See the appendix for
more information on WPA user authentication and WPA encryption.
If you don’t have an external RADIUS server, you should use WPA-PSK (WPA -Pre-Shared
Key). WPA-PSK only requires a single (identical) password entered into each WLAN
member. As long as the passwords match, a client will be granted access to a WLAN.
Note: You can’t use the Local User Database for authentication when you select
WPA.
6.5.1 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 be between 8 and 63 printable characters (including spaces; alphabetic
characters are case-sensitive).
2 The AP checks each client’s password and (only) allows it to join the network if the
passwords match.
3 The AP derives and distributes keys to the wireless clients.
4
The AP and wireless clients use the TKIP encryption process to encrypt data exchanged
between them.
