connection
AD_HOC This is the mode in which computers
communicate with each other directly, rather
than via access points.

INFRASTRUCTURE
(infrastructure mode)
This is the mode in which communications
are performed via the access point.

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.

Open System

OPEN
This is an authentication of wireless signals
employing a public key encryptosystem.

Shared Key/
SHARED
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”.

WPA-PSK
This is a standard covering encryption
methods used in wireless LAN. It provides
greater security than WEP, and has functions
such as a user authentication function and also
TKIP (encryption protocol) which automatically
changes the encryption key at fixed intervals.
50
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.
17/

TKIP Abbreviation for Temporal Key Integrity
Protocol.
This encryption protocol provides even
greater security than WEP because
it changes the encryption key at fixed
intervals.

AES These are the US Government’s next-
generation standard encryption methods,
the selection work of which is performed
by the National Institute of Standards and
Technology (NIST).
