Authentication And Encryption For Wireless Users Only - Brother MFC-9840CDW Network User's Manual

Authentication and encryption for wireless users only

Authentication method
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), 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 and CMIC encryptions.
Encryption methods
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.
TKIP
TKIP (Temporal Key Integrity Protocol) provides per-packet key mixing a message integrity check and re-
keying mechanism.
AES
AES (Advanced Encryption Standard) is Wi-Fi
CKIP
The original Key Integrity Protocol for LEAP by Cisco Systems, Inc.
®
authorized strong encryption standard.
