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®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.
