Network key
Data that is used for encrypting data in data
communication. The personal computer uses the
same network key both for data encryption and
decryption, therefore, it is necessary to set the
same network key as the other side of
communication.
Network name (SSID: Security Set
Identifier)
When a wireless LAN network is configured,
grouping is performed to avoid interference or
data theft. This grouping is performed with
“Network name (SSID)”. In order to improve
security, the network key is set allowing no
communication unless “Network name (SSID)”
coincides with the network key.
Open system authentication
One of network authentication types for wireless
LAN. Since there is no check of network key upon
authentication, clients can connect to the access
point without submitting correct network keys.
However, in case of actual communications, the
same network key must be set. Open system
authentication is sometimes called Open key
authentication.
PPPoE (Point to Point Protocol over
Ethernet)
A method of allowing the authentication protocol
adopted in telephone line connection (PPP) to
be used over an Ethernet.
Protocol
A procedure or rule of delivering data among
computers. Ordered data communication is
allowed by making all conditions required for
communication including the method of data
transmission/reception and actions upon
communication errors into procedures.
Shared key authentication
One of the network authentication types for
wireless LAN. Upon authentication, the access
point checks whether the same network key is
set to the client. If the client uses a wrong network
key or the network key itself is not set,
authentication is unsuccessful, allowing no
communications with the access point.
SSID (Security Set Identifier)
See “Network name”
Subnet mask
TCP-IP network is controlled by being divided
into multiple smaller networks (subnets). IP
address consists of the subnet address and the
address of each computer. Subnet mask defines
how many bits of IP address comprise the subnet
address. The same value shall be set among
computers communicating with each other.
TCP/IP (Transmission Control Protocol/
Internet Protocol)
A standard protocol of the Internet.
Wi-Fi
Indicates that the interconnectivity test of the
organization which guarantees the compatible
connection of wireless LAN (Wi-Fi Alliance) has
been passed.
