Specifications
WPA (Wi-Fi Protected Access)
This is a security standard established by the Wi-Fi
Alliance. In addition to the conventional SSID (network
name) and WEP key (network key), it also uses a user
identification function and encrypting protocol for
stronger security.
WPA2 (Wi-Fi Protected Access 2)
This is a new version of the WPA established by the
Wi-Fi Alliance, compatible with more secure AES
encryption.
WPA-PSK/WPA2-PSK (Pre-shared Key)
This is a simple authentication system for mutual
authentication when a preset character string matches
on the wireless LAN access point and client.
Passphrase
This refers to the code key used for WPA-PSK/WPA2-
PSK authentication, a WPA authentication method.
TKIP (Temporal Key Integrity Protocol)
This is a network key used for WPA. The encryption
algorithm is RC4, the same as for WEP, but the security
level is increased by changing the network key used
for encryption for each packet.
AES (Advanced Encryption Standard)
This is a next generation standard encryption method
replacing the current DES and 3DES, and because of
its high security it is expected to be applied widely
to wireless LANs in the future. It uses the “Rijndael”
algorithm developed by two Belgian cryptographers to
divide the data into blocks of fixed lengths and encrypt
each block. It supports data lengths of 128, 192 and
256 bits and key lengths of 128, 192 and 256 bits as
well, offering extremely high encryption security.
Infrastructure Communications
“Infrastructure Communications” refers to networks
using wireless LAN access points.
This function can be used to connect to the Internet or
a wired LAN via a wireless LAN access point. Wireless
LAN access points include wireless broadband
routers.
Network Names
(SSID: Security Set Identifier)
When forming wireless LAN networks, groups are
formed to prevent interference, data theft, etc.
This grouping is done by “SSID” or “Security Set
Identifiers”. For further security, a WEP key is set and
signal transfer is not possible unless the SSID and
WEP key match.
WEP Key (Network Key)
This is key information used for encrypting data when
conducting data transfer. On the ASD-51W, the same
WEP key is used for data encryption and decryption,
so the same WEP key must be set on both devices in
order for communications to be established between
them.
WPS (Wi-Fi Protected Setup)
This is a standard drawn up by the Wi-Fi Alliance to
ease the task of setting up wireless LAN connections
and configuring security.
There are two methods: push-button and PIN (Personal
Identification Number) code.
