Authentication and Encryption methods for an enterprise wireless network
10
An enterprise wireless network is a large network, for example using your machine in a business enterprise
wireless network with IEEE 802.1x support. If you configure your machine in an IEEE 802.1x supported
wireless network, you can use the following authentication and encryption methods:
Authentication methods
10
 LEAP (For wireless network)
Cisco LEAP (Light Extensible Authentication Protocol) has been developed by Cisco Systems, Inc. which
uses a user ID and password for authentication.
 EAP-FAST
EAP-FAST (Extensible Authentication Protocol-Flexible Authentication via Secured Tunnel) has been
developed by Cisco Systems, Inc. which uses a user ID and password for authentication, and symmetric
key algorithms to achieve a tunnelled authentication process.
The Brother machine supports the following inner authentication methods:
• EAP-FAST/NONE
• EAP-FAST/MS-CHAPv2
• EAP-FAST/GTC
 PEAP
PEAP (Protected Extensible Authentication Protocol) has been developed by Microsoft Corporation,
Cisco Systems and RSA Security. PEAP creates an encrypted SSL (Secure Sockets Layer)/
TLS (Transport Layer Security) tunnel between a client and an authentication server, for sending a
user ID and password. PEAP provides mutual authentication between the server and the client.
The Brother machine supports the following inner authentication methods:
• PEAP/MS-CHAPv2
• PEAP/GTC
 EAP-TTLS
EAP-TTLS (Extensible Authentication Protocol Tunnelled Transport Layer Security) has been developed
by Funk Software and Certicom. EAP-TTLS creates a similar encrypt SSL tunnel to PEAP, between a
client and an authentication server, for sending a user ID and password. EAP-TTLS provides mutual
authentication between the server and the client.
The Brother machine supports the following inner authentication methods:
• EAP-TTLS/CHAP
• EAP-TTLS/MS-CHAP
• EAP-TTLS/MS-CHAPv2
• EAP-TTLS/PAP
 EAP-TLS
EAP-TLS (Extensible Authentication Protocol Transport Layer Security) requires digital certificate
authentication both at a client and an authentication server.
