AP-7131 Access Point Product Reference Guide
(specified in RFC 1510) to authenticate users/clients in a wireless network environment and to
securely distribute the encryption keys used for both encrypting and decrypting.
A basic understanding of RFC 1510 Kerberos Network Authentication Service (V5) is helpful in
understanding how Kerberos works. By default, WLAN devices operate in an open system network
where any wireless device can associate with an AP without authorization. Kerberos requires device
authentication before access to the wired network is permitted.
For detailed information on Kerbeors configurations, see Configuring Kerberos Authentication on
page 6-8.

1.1.12.2 EAP Authentication

The Extensible Authentication Protocol (EAP) feature provides access points and their associated
MUs an additional measure of security for data transmitted over the wireless network. Using EAP,
authentication between devices is achieved through the exchange and verification of certificates.
EAP is a mutual authentication method whereby both the MU and AP are required to prove their
identities. Like Kerberos, the user loses device authentication if the server cannot provide proof of
device identification.
Using EAP, a user requests connection to a WLAN through the access point. The access point then
requests the identity of the user and transmits that identity to an authentication server. The server
prompts the AP for proof of identity (supplied to the by the user) and then transmits the user data
back to the server to complete the authentication process.
An MU is not able to access the network if not authenticated. When configured for EAP support, the
access point displays the MU as an EAP station.
EAP is only supported on mobile devices running Windows XP, Windows 2000 (using Service Pack #4)
and Windows Mobile 2003. Refer to the system administrator for information on configuring a Radius
Server for EAP (802.1x) support.
For detailed information on EAP configurations, see Configuring 802.1x EAP Authentication on page
6-11.

1.1.12.3 WEP Encryption

All WLAN devices face possible information theft. Theft occurs when an unauthorized user
eavesdrops to obtain information illegally. The absence of a physical connection makes wireless links
particularly vulnerable to this form of theft. Most forms of WLAN security rely on encryption to
various extents. Encryption entails scrambling and coding information, typically with mathematical
