Shared Key
This is a secret key encryptosystem for wireless signals in which authentication is
performed with a key pre-set in the WEP.
Other terms for this method, in which the same key is used for both encryption and
decryption, are “shared key encryptosystem” and “common key encryptosystem”.
SSID
Abbreviation for Service Set ID. The SSID identification code must be set to distinguish
equipment included in a wireless LAN that uses access points from equipment not
included in that LAN.
This may appear as the “ESSID” or the “network name” for wireless LAN cards made
by some manufacturers.
Subnet mask
This limits the range of the IP addresses assigned to computers in order to divide the
network into a number of sections during TCP/IP connection. The value used to divide
the network at this time is called the subnet mask.
TCP/IP
Abbreviation for Transmission Control Protocol/Internet Protocol. This is the standard
internet protocol.
This protocol is a set of rules and agreements governing data communications
between computers.
WEP
Abbreviation for Wired Equivalent Privacy. This is a method for encrypting
communication data. The encryption key is created and notified only to the
communicating user, so the communication data cannot be decrypted by a third party.
