Wi-Fi Protected Access (WPA)
WPA employs a combination of several technologies to provide
an enhanced security solution for 802.11 wireless networks.
The SMC2552W-G supports the following WPA components and
features:
IEEE 802.1x and the Extensible Authentication Protocol
(EAP):
WPA employs 802.1x as its basic framework for user
authentication and dynamic key management. The 802.1x client
and RADIUS server should use an appropriate EAP type—such
as EAP-TLS (Transport Layer Security), EAP-TTLS (Tunneled
TLS), or PEAP (Protected EAP)—for strongest authentication.
Working together, these protocols provide “mutual authentication”
between a client, the access point, and a RADIUS server that
prevents users from accidentally joining a rogue network. Only
when a RADIUS server has authenticated a user’s credentials will
encryption keys be sent to the access point and client.
