B
Authentication and encryption for wireless users only
B
Authentication method
B
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
B
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.
