AES (Advanced Encryption Standard)
An encryption protocol employed by the
wireless LAN encryption systems WPA and
WPA2. AES has more advanced security
functions than TKIP.
Default gateway
When communicating with devices that exist on
a different network, the data is first transferred
to a node (relay point) called a gateway.
However, when the gateway to which the data
should be transmitted is not known, the data is
transferred to the most typical node called the
default gateway.
DHCP (Dynamic Host Configuration
Protocol)
A system for automatically allocating
configuration data required for an Internet
connection.
IP address
IP addresses usually comprise four groups of up
to three digits each, separated by a period (such
as 192.168.239.1). All devices on a network
must have an IP address.
MAC address (Media Access Control
Address)
A unique number set to identify a network
interface on a network. A unique address is
assigned to each interface connected to a
network.
SSID (Service Set Identifier)
The name used by a wireless LAN to identify a
specific network. The same SSID is set for both
the wireless LAN router and the device with
wireless LAN functions, and wireless
communication is possible between devices
with matching SSID.
Subnet mask
Part of an IP address that identifies the subnet, a
smaller group on the network.
30 GB
TKIP (Temporal Key Integrity
Protocol)
An encryption protocol employed by the
wireless LAN encryption systems WPA and
WPA2. TKIP prevents decoding of encryption
keys and spoofing, and has more advanced
security functions than WEP.
WEP (Wired Equivalent Privacy)
A data encryption system employed by wireless
LAN. WEP technology uses the same 64-bit or
128-bit encryption key for both devices
communicating over a wireless LAN to prevent
data from being decoded by other devices.
WPA (Wi-Fi Protected Access)
The wireless LAN encryption standard
advocated by the wireless LAN industry group
Wi-Fi Alliance. The WPA standard features
stronger security than WEP.
WPA2 (Wi-Fi Protected Access 2)
The new wireless LAN encryption standard
advocated by the wireless LAN industry group
Wi-Fi Alliance. The WPA2 standard features
even stronger security than WPA.
