Wireless network terms and concepts

Security terms

Authentication and encryption

Most wireless networks use some kind of security settings. These security settings define the authentication
(how the device identifies itself to the network) and encryption (how the data is encrypted as it is sent on the
network). If you do not correctly specify these options when you are configuring your Brother wireless
machine, it will not be able to connect to the wireless network. Therefore care must be taken when
configuring these options. Please see Supported protocols and security features uu page 103 for which
authentication and encryption methods your Brother wireless machine supports.

Authentication and Encryption methods for a personal wireless network

A personal wireless network is a small network, such as a home wireless network, without IEEE 802.1x
support.
If you want to use your machine in an IEEE 802.1x supported wireless network, see Authentication and
Encryption methods for an enterprise wireless network uu page 94.
Authentication methods
 Open system
Wireless devices are allowed to access the network without any authentication.
 Shared key
A secret pre-determined key is shared by all devices that will access the wireless network.
The Brother wireless machine uses the WEP key as the pre-determined key.
WPA-PSK/WPA2-PSK

Enables a Wi-Fi Protected Access
wireless machine to associate with access points using TKIP for WPA-PSK or AES for WPA-PSK and
WPA2-PSK (WPA-Personal).
Encryption methods
 None
No encryption method is used.
 WEP
When using WEP (Wired Equivalent Privacy), the data is transmitted and received with a secure key.
 TKIP
TKIP (Temporal Key Integrity Protocol) provides per-packet key mixing, a message integrity check and
rekeying mechanism.
 AES
AES (Advanced Encryption Standard) provides stronger data protection by using a symmetric-key
encryption.
