Appendix D: Glossary
Default Password
A password set by the manufacturer that is unique to each device and is used to
Generate a Default Encryption Key (DEK). The DEK is used only for the purpose of
encrypting management commands that change the NEK so that the NEK is never
sent in the clear over the powerline.
DHCP
Dynamic Host Configuration Protocol is a method in which IP addresses are
assigned by server dynamically to the clients on the network. DHCP is used for
Dynamic IP Addressing and requires a dedicated DHCP server on the network.
Encryption Key (EK)
64-bit pattern generated by a key derivation function. An EK is used in an
encryption algorithm to add security to transmissions between HomePlug devices in
a logical network.
Ethernet
Ethernet is a 10/100Mbps network that runs over dedicated home/office wiring. Users
must be wired to the network at all times to gain access.
Gateway
A gateway is a hardware and software device that connects two dissimilar systems,
such as a LAN and a mainframe. In Internet terminology, a gateway is another name
for a router. Generally a gateway is used as a funnel for all traffic to the Internet.
IEEE
The Institute of Electrical and Electronics Engineers. The IEEE describes itself as
“the world’s largest technical professional society—promoting the development and
application of electro technology and allied sciences for the benefit of humanity, the
advancement of the profession, and the wellbeing of our members.”
Local Area Network (LAN)
A LAN is a group of computers, each equipped with the appropriate network adapter
card connected by cable/air, that share applications, data, and peripherals. All
connections are made via cable or wireless media, but a LAN does not use
telephone services. It typically spans a single building or campus.
Logical Network
Two or more HomePlug devices that share a common Network Encryption Key
(NEK) and that communicate with encrypted transmissions.
Network
A network is a system of computers that is connected. Data, files, and messages can
be transmitted over this network. Networks may be local or wide area networks.
Network Password
A password set by the user that generates the NEK and defines the user’s logical
