Wi-Fi Protected Access

 (WPA)

WPA employs a combination of several technologies to provide 
an enhanced security solution for 802.11 wireless networks. 

The SMC2555W-AG 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.
