Authentication and encryption for wireless users only E
Authentication method E
The Brother machine supports the following 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 machine uses the WEP keys as the pre-determined key.
 WPA-PSK/WPA2-PSK
Enables a Wi-FI Protected Access Pre-Shared Key (WPA-PSK/WPA2-PSK), which enables
the Brother wireless machine to associate with access points using TKIP for WPA-PSK or AES
for WPA-PSK and WPA2-PSK (WPA-Personal).
 LEAP
Cisco LEAP (Light Extensible Authentication Protocol) has been developed by Cisco Systems,
Inc. and enables the Brother wireless product to associate with access points using CKIP
encryptions.
 EAP-FAST
EAP-FAST (Extensible Authentication Protocol - Flexible Authentication via Secured Tunnel)
has been developed by Cisco Systems, Inc. which uses user ID and password for
authentication, and symmetric key algorithms to achieve a tunneled authentication process.
The Brother machine supports the following inner authentications:
• EAP-FAST/NONE
MS-CHAPv2 is used for Provisioning, and the method of EAP-FAST corresponding to
second phase authentication method.
• EAP-FAST/MS-CHAPv2
Method of EAP-FAST corresponding to CCXv4 that uses MS-CHAPv2 for the inner
method.
• EAP-FAST/GTC
Method of EAP-FAST corresponding to CCXv4 that uses GTC for the inner method.
Encryption methods E
Encryption is used to secure the data that is sent over the wireless network. The Brother machine
supports the following encryption methods:
 WEP
By using WEP (Wired Equivalent Privacy), the data is transmitted and received with a secure
key.
