WPA/WPA2-Personal
WPA (Wi-Fi Protected Access) and WPA2 represent significant improvements over the WEP encryption method.
WPA is a security standard based on 802.11i draft 3, while WPA2 is based on the fully ratified version of 802.11i.
The initial vector is transmitted, encrypted, and enhanced with its 48 bits, twice as long as WEP. The key is
regularly changed so that true session is secured.
Even though AES encryption is only included in the WPA2 standard, it is widely available in the WPA security
mode of some wireless APs and clients as well. The AWK-3131-RCC also supports AES algorithms in WPA and
WPA2 for better compatibility.
Personal versions of WPA/WPA2, also known as WPA/WPA-PSK (Pre-Shared Key), provide a simple way of
encrypting a wireless connection for high confidentiality. A Passphrase is used as a basis for encryption
methods (or cipher types) in a WLAN connection. The passphrases should be complicated and as long as
possible. There must be at least 8 ASCII characters in the Passphrase, and it could go up to 63. For security
reasons, this passphrase should only be disclosed to users who need it, and it should be changed regularly.
WPA type
Setting
Description Factory Default
Personal Provides Pre-Shared Key-enabled WPA and WPA2 Personal
Enterprise Provides enterprise-level security for WPA and WPA2
Encryption method
Setting
Description Factory Default
TKIP Temporal Key Integrity Protocol is enabled TKIP
AES Advance Encryption System is enabled
Mixed* Provides TKIP broadcast key and TKIP+AES unicast key for
some legacy AP clients. This option is rarely used.
*This option is available in AP/Master mode only, and does not support AES-enabled clients.
Passphrase
Setting
Description Factory Default
8 to 63 characters Master key to generate keys for encryption and decryption None
Key renewal (for AP/Master mode only)
Setting
Description Factory Default
60 to 86400 seconds
(1 minute to 1 day) Specifies the time period of group key renewal 3600 (seconds)
NOTE The key renewal value dictates how often the wireless AP encryption keys should be changed. The security
level is generally higher if you set the key renewal value to a shorter number, which forces the encryption keys
to be changed more frequently. The default value is 3600 seconds (6 minutes). Longer time periods can be
considered if the line is not very busy.
