4.11. Wireless Authenticator and Authentication Server (hostapd)

The Authenticator is the software running on the wireless access point that translates the authentication and key management protocols between the wireless client (known as the supplicant) and the RADIUS server (known as the authentication server).

The Authenticator and Authentication Server used in SISO is HostAP's [29] hostapd. This section describes the installation on SISO.
