WPA/WPA2 Authentication: Enterprise-level User

Authentication via 802.1x/EAP and RADIUS

Figure B-3: WPA/WPA2 Overview

IEEE 802.1x offers an effective framework for authenticating and controlling user traffic to a

protected network, as well as providing a vehicle for dynamically varying data encryption keys via

EAP from a RADIUS server, for example. This framework enables using a central authentication

server, which employs mutual authentication so that a rogue wireless user does not join the

network.

It is important to note that 802.1x does not provide the actual authentication mechanisms. When

using 802.1x, the EAP type, such as Transport Layer Security (EAP-TLS), or EAP Tunneled

Transport Layer Security (EAP-TTLS), defines how the authentication takes place.

Note: For environments with a Remote Authentication Dial-In User Service (RADIUS)

infrastructure, WPA supports Extensible Authentication Protocol (EAP). For environments

without a RADIUS infrastructure, WPA supports the use of a pre-shared key.

Together, these technologies provide a framework for strong user authentication.

Windows XP implements 802.1x natively, and several NETGEAR switch and wireless access

point products support 802.1x.
