10 Glossary
CHAP: Challenge Handshake Authentication Protocol. Security feature
supported on lines using PPP encapsulation that prevents
unauthorized access. CHAP does not itself prevent unauthorized
access, but merely identifies the remote end. The router or access
server then determines whether that user is allowed access.
EAP: Extensible Authentication Protocol. Framework that supports multiple,
optional authentication mechanisms for PPP, including clear text
passwords, challenge-response, and arbitrary dialog sequences.
LEAP: Lightweight Extensible Authentication Protocol is a Cisco proprietary
EAP-Type. It is designed to overcome some basic wireless
authentication concerns through Mutual Authentication and the use
of dynamic WEP keys.
MD5: MD5 is an EAP-Type for authentication. It is analogous to the PPP
CHAP protocol. A challenge string is sent from the Authentication
Server to the Supplicant in the MD5-Challenge Request. The
challenge string with the user password is hashed using MD5 and the
hash is returned in the MD5-Challenge Response. The Authentication
Server performs the same hash and compares the result with that
returned by the Supplicant to determine whether the authentication is
a Success.
PAP: Password Authentication Protocol. Authentication protocol that allows
PPP peers to authenticate one another. The remote router attempting
to connect to the local router is required to send an authentication
request. Unlike CHAP, PAP passes the password and the host name
or username in the clear (unencrypted). PAP does not itself prevent
unauthorized access but merely identifies the remote end. The router
or access server then determines whether that user is allowed access.
PAP is supported only on PPP lines.
39
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.
TTLS: Tunneled TLS is an EAP-Type for authentication that employs a
two-phase authentication process. In the first phase the
Authentication Server is authenticated to the Supplicant. Using TLS,
a secure channel is established through which the Supplicant can be
authenticated to the Authentication Server using legacy PPP
authentication protocols such as PAP, CHAP, and MS-CHAP. TTLS
has the advantage over TLS that it only requires a certificate at the
Authentication Server. It also makes possible forwarding of
Supplicant requests to a legacy RADIUS server. TTLS 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.
40
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.
