Authentication And Encryption For Wireless Users Only - Brother MFC MFC-7840W User 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/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 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.
CMIC
CMIC (Cisco Message Integrity Check) is the message integrity check mechanism for LEAP
by Cisco Systems, Inc.
Network key
There are some rules for each security method:
164
®
authorized strong encryption standard.
