GL
SSID
(Service Set Identifier) The unique name shared among all devices in a wireless
LAN (WLAN).
station
In IEEE 802.11 networks, any device that contains an IEEE 802.11-compliant
media access control and physical layers. See also, 802.11x.
TKIP
(Temporal Key Integrity Protocol) A wireless encryption protocol that fixes the
known problems in the Wired-Equivalent Privacy (WEP) protocol for existing
802.11 products. Like WEP, TKIP uses RC4 ciphering, but adds functions such
as a 128-bit encryption key, a 48-bit initialization vector, a new message
integrity code (MIC), and initialization vector (IV) sequencing rules to provide
better protection. See also, 802.11x and WEP.
TLS
(Transport Layer Security Protocol) An authentication and encryption protocol
that is the successor to the Secure Sockets Layer (SSL) protocol for private
transmission over the Internet. Defined in RFC 2246, TLS provides mutual
authentication with non-repudiation, encryption, algorithm negotiation, secure
key derivation, and message integrity checking. TLS has been adapted for use in
wireless LANs (WLANs) and is used widely in IEEE 802.1X authentication. See
also, 802.1X.
TTLS
(Tunneled Transport Layer Security) An Extensible Authentication Protocol (EAP)
sub-protocol developed by Funk Software, Inc. for 802.1X authentication. TTLS
uses a combination of certificate and password challenge and response for
authentication. The entire EAP sub-protocol exchange of attribute-value pairs
takes place inside an encrypted transport layer security (TLS) tunnel. TTLS
supports authentication methods defined by EAP, as well as the older Challenge
Handshake Authentication Protocol (CHAP), Password Authentication Protocol
(PAP), Microsoft CHAP (MS-CHAP), and MS-CHAPV2. Compare EAP-TLS;
PEAP. See also, 802.1X, connectivity, MS-CHAP, PAP and PEAP.
