| 802.1x |
|
The 802.1X standard is designed to enhance the security of wired and wireless local area networks that follow the IEEE standard. 802.1X provides authentication to AirPennNet, which involves communications between a supplicant (laptop or handheld), authenticator (wireless access point), and authentication server allowing a user to be authenticated by a PennNet trusted central authority using their PennKey and password.
|
| Access Point (AP) |
|
A communication hub on a network located
within the wireless connectivity area that relays information between the wired
network and a user's wireless device.
|
| DHCP |
|
Dynamic Host Configuration Protocol (DHCP)
is used to assign dynamic (temporary) IP addresses to individual devices on
a network. With dynamic addressing, a device can be assigned a different IP
address
each
time it
connects to the network.
This strategy simplifies network administration allowing new devices to access
to the network without first having to manually assign an IP address.
|
| IP Address |
|
An Internet Protocol (IP) address is a unique numeric
identifier for a computer or device on a network differentiating it from
all other devices. IP Addresses are used to communicate between computers and
other devices over the Internet.
|
| LAN |
|
A local-area network (LAN) is a computer network
that extends over a small area.
|
| MAC Address |
|
A unique identifier assigned to a computing device
on a network. Some wireless installations on Penn's campus use the MAC address
of
your wireless
card to identify
you as an authorized network user.
|
| SSID |
|
An SSID, or Service Set Identifier, is the name used by a wireless card to identify itself to a specific wireless network. This information may also be referred to as the "Network Name."
|
| SSL |
|
Secure Sockets Layer (SSL) is a method of encrypting
data using a public key. Both Internet Explorer and Netscape support SSL,
and many Web sites use this encryption method to transfer confidential
user information, such as credit card numbers. By convention, URLs that require
an SSL connection
start with https:// instead of http://.
|
| Supplicant |
|
In an authentication system, a supplicant refers to the machine attempting to gain access to the network.
|
| TCP/IP |
|
TCP/IP is the underlying communication
technology behind the Internet and communications between computers on a
network.
