Appendix B: 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 Powerline 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 Powerline devices that share a common Network Encryption Key
(NEK) and that communicate with encrypted transmissions.
