A set of International Telecommunications Union Telecommunication Standardization Sector

(ITU-T) standards that dene 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

nding 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, dened in RFC 2104, for keyed hashing

for message authentication. HMAC is used with MD5 and the secure hash algorithm (SHA).

hashed message authentication code

See HMAC.

homologation

The process of certifying a product or specication to verify that it meets regulatory

standards.

IAS

Internet Authentication Service. Microsoft’s RADIUS server.

Industry Canada. The Canadian governing body for telecommunications.

ICV
