IEEE 802.1x Authentication
9
IEEE 802.1x is an IEEE standard for wired and wireless networks that limits access from unauthorized
network devices. Your Brother machine (supplicant) sends an authentication request to a RADIUS server
(Authentication server) through your access point (authenticator). After your request has been verified by the
RADIUS server, your machine can access the network.
Authentication methods
9
 LEAP (For wireless network)
Cisco LEAP (Lightweight 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 Tunneling) has been
developed by Cisco Systems, Inc. which uses a user ID and password for authentication, and symmetric
key algorithms to achieve a tunneled authentication process.
The Brother machine supports the following inner authentication methods:
• EAP-FAST/NONE
• EAP-FAST/MS-CHAPv2
• EAP-FAST/GTC
 EAP-MD5 (For wired network)
EAP-MD5 (Extensible Authentication Protocol-Message Digest Algorithm 5) uses a user ID and password
for challenge-response authentication.
 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 authentications:
• PEAP/MS-CHAPv2
• PEAP/GTC
