WPA authentication

The IEEE 802.1X standard specifies the WPA protocol as an access control method for work Wi-Fi networks. You can also

use WPA authentication in small-office environments and home environments where you cannot configure server-based

authentication.

To configure WPA authentication, you can use the PSK protocol to send a passphrase that matches the key or passphrase

for the wireless access points to a

Wi-Fi enabled BlackBerry device. The access points and device use a passphrase to

generate layer 2 encryption keys. The passphrase can be up to 256 bits. All access points and each device in your

organization must share the same passphrase.

The PSK protocol is designed to use TKIP keys or AES-CCMP keys to protect communications over the enterprise Wi-Fi

network. The PSK protocol relies on the passphrase to control whether a device can access the work Wi-Fi network.

The device is compatible with the WPA-Personal specification and WPA2-Personal specification.

For more information about configuring the device to support WPA authentication, see the BlackBerry Enterprise Server

Administration Guide.
