- Authenticator: It is a network device that acts as a proxy between supplicant and
authentication server. It passes around information, verifies information with the server,
and relays response to the supplicant.
The authenticator acts like a security guard to a protected network. The supplicant is not
allowed access through the authenticator to the protected side of the network until the
supplicant’s identity has been validated and authorized. With 802.1X authentication, a
supplicant and an authenticator exchange EAP (Extensible Authentication Protocol, an
authentication framework widely used by IEEE). Then the authenticator forwards this
information to the authentication server for verification; if the authentication server confirms
the request, the supplicant (client device) will be allowed to access resources located on the
protected side of the network.
RADIUS: It is a networking protocol that provides authentication, authorization and
accounting management for devices to connect and use a network service.
