group transient key
H.323
A set of International Telecommunications Union Telecommunication Standardization Sector
(ITU-T) standards that define a framework for the transmission of real-time voice signals over IP
packet-switched networks.
hash
A one-way algorithm from whose output the input is computationally infeasible to determine. With a
good hashing algorithm you can produce identical output from two identical inputs, but finding two different
inputs that produce the same output is computationally infeasible. Hash functions are used widely in
authentication algorithms and for key derivation procedures.
HiperLAN
High-performance radio local area network. A set of wireless LAN (WLAN) communication
standards used primarily in European countries and adopted by the European Telecommunications Standards
Institute (ETSI).
HMAC
Hashed message authentication code. A function, defined in RFC 2104, for keyed hashing for
message authentication. HMAC is used with MD5 and the secure hash algorithm (SHA).

Hewlett-Packard Open View
homologation
The process of certifying a product or specification to verify that it meets regulatory
standards.
HPOV
Hewlett-Packard Open View. The umbrella network management system (NMS) family of products
from Hewlett-Packard. The Nortel WLAN 2300 system WLAN Management Software tool suite interacts
with the HPOV Network Node Manager (NNM).
HTTPS
Hypertext Transfer Protocol over Secure Sockets Layer. An Internet protocol developed by
Netscape to encrypt and decrypt network connections to Web servers. Built into all secure browsers, HTTPS
uses the Secure Sockets Layer (SSL) protocol as a sublayer under the regular HTTP application layer, and uses
port 443 instead of HTTP port 80 in its interactions with the lower layer, TCP/IP. See also SSL.

IAS
Internet Authentication Service. Microsoft's RADIUS server.
IC
Industry Canada. The Canadian governing body for telecommunications.
ICV
Integrity check value. The output of a message integrity check.
IE
See WPA IE.
IEEE
Institute of Electrical and Electronic Engineers. An American professional society whose standards for
the computer and electronics industry often become national or international standards. In particular, the IEEE
802 standards for LANs are widely followed.
IGMP
Internet Group Management Protocol. An Internet protocol, defined in RFC 2236, that enables an
Internet computer to report its multicast group membership to neighboring multicast routers. Multicasting
allows a computer on the Internet to send content to other computers that have identified themselves as
interested in receiving it.
