Glossary PEAP: Protected Extensible Authentication Protocol is a two-phase
authentication like TLS. In the first phase the Authentication Server is
authenticated to the Supplicant. Using TLS, a secure channel is
established through which any other EAP-Type can be used to
authenticate the Supplicant to the Authentication Server during the
second phase. A certificate is only required at the Authentication
Server. PEAP also supports identity hiding where the Authenticator
is only aware of the anonymous username used to establish the TLS
channel during the first phase but not the individual user authenticated
during the second phase.
SSID: Name of wireless network.
TLS: TLS is an EAP-Type for authentication based upon X.509 certificates.
Because it requires both the Supplicant and the Authentication
Server to have certificates, it provides explicit Mutual Authentication
and is resilient to man-in-the-middle attacks. After successful
authentication a secure TLS link is established to securely
communicate a unique session key from the Authentication Server
to the Authenticator.
WPA: Wi-Fi Protected Access is a replacement security standard for WEP. It
is a subset of the IEEE 802.11i standard being developed. WPA
makes use of TKIP to deliver security superior to WEP. 802.1X access
control is still employed. The Authentication Server provides the
material for creating the keys.
