For WPA-PSK
WiFi-Protected Access: WPA-PSK is useful
for small places such as home environment
without having authentication servers. It
allows the use of manually-entered keys or
passwords and is designed to be easy to set
up for home users.
Format:
Choose the typing method of encryption key.
You have to click either Hexadecimal digits
or ASCII characters and type the keys on
the field of Pre-Share Key.
Pre-Share Key: Please type the key to be
between 8 and 63 characters, or 64
hexadecimal digits. Only the devices with a
matching key that you set here can join this
network.
WPA Group Rekey Interval: Type in the
time for the WAP group rekey interval. The
unit is second.
Data Encryption (WPA): Select the data
encryption for the WPA mode. There are
three types that you can choose, TKIP, AES,
TKIP+AES.
TKIP takes the original master key only
as a starting point and derives its
encryption keys mathematically from this
master key. Then it regularly changes and
rotates the encryption keys so that the
same encryption key will be never used
twice.
AES provides security between client
workstations operating in ad hoc mode. It
uses a mathematical ciphering algorithm
that employs variable key sizes of 128, 192
or 256 bits.
TKIP+AES combines the features and
functions of TKIP and AES.
After finished settings, click Apply for
activation.
