Chapter 3 — Configuring the CV60

WPA2 runs in 802.1x (Enterprise) mode or PSK (Pre-Shared

Key) mode:

• For WPA2-802.1x mode, WPA2 requires authentication in

two phases; the first is an open system authentication and the

second uses 802.1x and an Extensible Authentication

Protocol (EAP) authentication method.

• In PSK mode, WPA2 provides user authentication using a

shared key between the authenticator and the CV60. WPA2-

PSK is a good solution for small offices or home offices that

do not want to use an authentication server.

Using 802.1x Security

802.1x security provides centralized user authentication using an

authentication server, authenticators (access points), and

supplicants (wireless devices). These components communicate

using an EAP authentication type, such as TLS (Transport Layer

Security) or PEAP (Protected Extensible Authentication

Protocol). 802.1x security provides data encryption using

dynamic key management.

To use 802.1x security, you need:

• an access point with an 802.11b/g or a/b/g radio.

• a CV60 with an 802.11b/g or a/b/g radio.

• an authentication server.

Using LEAP Security

Lightweight Extensible Authentication Protocol (LEAP), also

known as Cisco-Wireless EAP, provides username/password-

based authentication between a wireless client and a RADIUS

server. In the 802.1x framework, traffic cannot pass through an

Ethernet hub or wireless network access point until it successfully

authenticates itself.

The station must identify itself and prove that it is an authorized

user before it is actually allowed to use the LAN. LEAP also

delivers a session key to the authenticated station, so that future

frames can be encrypted with a key that is different than keys

used by other sessions.

To use LEAP security, you need:
