Encryption Methods - Brother Network MFC-7840W Network User's Manual

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. which
uses user ID and password for authentication.

Encryption methods

Encryption is used to secure the data that is sent over the wireless network. The Brother wireless machine
supports the following encryption methods:
None
No encryption method is used.
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
rekeying mechanism.
AES
AES (Advanced Encryption Standard) is the Wi-Fi
CKIP
The original Key Integrity Protocol for LEAP by Cisco Systems, Inc.
Network key
There are some rules for each security method:
Open system/Shared key with WEP
This key is a 64-bit or 128-bit value that must be entered in an ASCII or hexadecimal format.
• 64 (40) bit ASCII:
Uses 5 text characters. e.g. "WSLAN" (this is case sensitive).
• 64 (40) bit hexadecimal:
Uses 10 digits of hexadecimal data. e.g. "71f2234aba"
• 128 (104) bit ASCII:
Uses 13 text characters. e.g."Wirelesscomms" (this is case sensitive)
• 128 (104) bit hexadecimal:
Uses 26 digits of hexadecimal data. e.g. "71f2234ab56cd709e5412aa2ba"
