Security modes in details
Features overview
The ARF45-PRO device enables to add Wi-Fi networking capability to devices
with the highest WPA2/802.11i enterprise-grade security and authentication
protocols.
Like the ARF45, the ARF45-PRO supports the WPA/WPA2 Personal mode
which is a security mode that uses pre-shared key (PSK) for authentication.
On top of that, the ARF45-PRO also supports the WPA/WPA2 Enterprise
mode which enables to meet the rigorous requirement of enterprise security
by leveraging the 802.1X authentication framework which in turns relies on
EAP and an authentication server (RADIUS server) to provide strong mutual
authentication between the client and the authentication server via an access
point.
The picture below depicts the deployment scheme in which are involved
three components: the WIFI client (for instance an ARF45-PRO) also called
the supplicant, the Access Point also called the authenticator and the
authentication RADIUS server in charge of performing the client
authentication.
