5. Specify the 802.1x information if you are using the 802.1X certification method.

Users that do not use this function or connecting to an open-wireless network please skip this

part.

A. EAP Method:

For Windows 2000 User: There are total 5 modes: PEAP, TLS/Smart Card, TTLS, EAP-FAST, and

MD5-Challenge.

For Vista User: There are total 4 modes: PEAP, TLS/Smart Card, EAP-FAST, and LEAP.

Please select an EAP method from the drop down list.

Items Information

PEAP

Protect Extensible Authentication Protocol. PEAP transport securely authenticates

data by using tunneling between PEAP clients and an authentication server. PEAP can

authenticate wireless LAN clients using only server-side certificates, thus simplifying

the implementation and administration of a secure wireless LAN.

TLS/Smart

Card

Transport Layer Security. Provides for certificate-based and mutual authentication of

the client and the network. It relies on client-side and server-side certificates to

perform authentication and can be used to dynamically generate user-based and

session-based WEP keys to secure subsequent communications between the WLAN

client and the access point.

TTLS

Tunneled Transport Layer Security. This security method provides for

certificate-based, mutual authentication of the client and network through an

encrypted channel. Unlike EAP-TLS, EAP-TTLS requires only server-side certificates.

EAP-FAST

Flexible Authentication via Secure Tunneling. It was developed by Cisco. Instead of

using a certificate, mutual authentication is achieved by means of a PAC (Protected

Access Credential) which can be managed dynamically by the authentication server.

The PAC can be supplied (distributed one time) to the client either manually or

automatically. Manually, it is delivered to the client via disk or a secured network

distribution method. Automatically, it is supplied as an in-band, over the air,

distribution. For tunnel authentication, only support "Generic Token Card"

authentication.

MD5-

Challenge

Message Digest Challenge. Challenge is an EAP authentication type that provides

base-level EAP support. It provides for only one-way authentication - there is no

mutual authentication of wireless client and the network.

LEAP

Light Extensible Authentication Protocol is an EAP authentication type used primarily

by Cisco Aironet WLANs. It encrypts data transmissions using dynamically generated

WEP keys, and supports mutual authentication.
