
Cipher Suite: You can chose use AES or TKIP with your WPA / WPA2 encryption
method

AES is short for “Advanced Encryption Standard”, The AES cipher is specified as a
number of repetitions of transformation rounds that convert the input plaintext into the
final output of ciphertext. Each round consists of several processing steps, including
one that depends on the encryption key. A set of reverse rounds are applied to
transform ciphertext back into the original plaintext using the same encryption key.

TKIP is short for “Temporal Key Integrity Protocol”, TKIP scrambles the keys using a
hashing algorithm and, by adding an integrity-checking feature, ensures that the keys
haven’t been tampered with.

Group Key Update Period: This time interval for re-keying GTK (broadcast/multicast
encryption keys) in seconds. Enter the time-length required; the default time is 600
seconds.

Master Key Update Period: This time interval for re-keying GMK (master key used
internally to generate GTKs) in seconds. Enter the time-length required; the default
time is 83400 seconds.

Key Type: Check on the respected button to enable either ASCII or HEX format for the
Pre-shared Key.

Pre-Shared Key: Enter the information for pre-shared key; the format of the
information shall according to the key type selected. Pre-shared key can be either
entered as a 256-bit secret in 64 HEX digits format, or 8 to 63 ASCII characters.

WPA-Enterprise (or WPA2-Enterprise) General Setting
The RADIUS authentication and encryption will be both enabled if this selected.
