XX
STBC
Space-Time Block Coding is a technique that helps improve error rates and reliability in
a system that is experiencing poor transmission performance.
STP
Spanning Tree Protocol—a link management protocol, operating at OSI layer 2, that
prevents bridging loops while permitting path redundancy in a bridged network.
Suite B
A set of cryptographic algorithms promulgated by the National Security Agency as part
of its Cryptographic Modernization Program.
SWLAN Secure Wireless Local Area Network
symmetric key encryption
A class of cryptographic algorithm in which a shared secret between two or more par-
ties is used to maintain a private connection between or among them.
Tactical Mesh Point Name of the Fortress ES210 model Mesh Point.
TCP
Transmission Control Protocol—defines a method for reliable (i.e., in order, with integ-
rity checking) delivery of data packets over a network; one of the founding protocols in
the TCP/IP suite of networking protocols.
TCP/IP
Transmission Control Protocol/Internet Protocol, also Internet Protocol Suite—the basic,
two-part communication protocol in use on the Internet (refer to IP and TCP).
TLS
Transport Layer Security—a two-part protocol that defines secure data transmission
between client/server applications communicating over the Internet. TLS Record Proto-
col uses data encryption to secure data transfer, and the TLS Handshake Protocol allows
the client and server to authenticate each other and negotiate the encryption method
to use before exchanging data.
Trusted Device
In Fortress products, a device that does not have the Secure Client installed but is
allowed network access through rules defined for it on the Fortress Mesh Point.
trusted hierarchy Refer to PKI.
UDP
User Datagram Protocol—defines a method for “best effort” delivery of data packets
over a network that, like TCP, runs on top of IP but, unlike TCP, does not guarantee the
order of delivery or provide integrity checking.
UI
User Interface—the means by which a human end user provides input to and receives
output from computer software.
ULA
Unique Local Address—an IPv6 globally unique unicast address (subnet identifier),
defined in IETF RFC 4193, intended for local (intranet) communications and not
intended to be routable on the Internet.
user authentication
A mechanism for requiring users to submit established credentials (user name and
password, smartcard, etc.) and checking the validity of these credentials before allow-
ing users to log on to a device or network.
user password
The password an end must enter in order to access a network or device that requires
user authentication (compare administrator password).
Vehicle Mesh Point Name of the Fortress ES820 model Mesh Point.
VLAN
Virtual Local Area Network—a collection of computers configured through software to
behave as though they are members of the same network, even though they may be
physically connected to separate subnets.
VoIP
Voice over IP, sometimes VOI (Voice over Internet)—any of several means for transmit-
ting audio communications over the Internet.
VPN
Virtual Private Network—a private network of computers connected, entirely or in part,
by public phone lines.
WAN
Wide Area Network—a collection of interconnected computers covering a large geo-
graphic area.
