684GLOSSARY

GMK	Group master key. A cryptographic key used to derive a group transient
	key (GTK) for the Temporal Key Integrity Protocol (TKIP) and Advanced
	Encryption Standard (AES).
greenfield network	An original deployment of a telecommunications network.
GRE tunnel	A virtual link between two remote points on a network, created by
	means of the Generic Routing Encapsulation (GRE) tunneling protocol.
	GRE encapsulates packets within a transport protocol supported by the
	network.
GTK	Group transient key. A cryptographic key used to encrypt broadcast and
	multicast packets for transmissions using the Temporal Key Integrity
	Protocol (TKIP) and Advanced Encryption Standard (AES).
group master key	See GMK.
group transient key	See GTK.
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).
hashed message	See HMAC.
