Challenge Handshake Authentication Protocol
See CHAP.
CHAP
Challenge Handshake Authentication Protocol. An authentication protocol that defines a
threeway handshake to authenticate a user (client). CHAP uses the MD5 hash algorithm to
generate a response to a challenge that can be checked by the authenticator. For wireless
connections, CHAP is not secure and must be protected by the cryptography in such
authentication methods as the Protected Extensible Authentication Protocol (PEAP) and
Tunneled Transport Layer Security (TTLS).
client
The requesting program or device in a client-server relationship. In a wireless LAN (WLAN),
the client (or supplicant) requests access to the services provided by the authenticator. See
also supplicant.
co-channel interference
See CCI.
collision domain
A single half-duplex IEEE 802.3 Carrier Sense Multiple Access with Collision Detection
(CSMA-CD) network. A collision occurs when two or more Layer 2 devices in the network
transmit at the same time. Ethernet segments separated by a Layer 2 switch are within
different collision domains.
