Authentication and encryption for wireless users only
D
Authentication method
D
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
D
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
®
authorized strong encryption standard.
±
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
D
There are some rules for each security method:
