WPA/WPA2-Personal
WPA (Wi-Fi Protected Access) and WPA2 are significantly improved encryption methods of WEP.
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 for added security.
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-4121 also supports AES
algorithms in WPA and WPA2 for better compatibility.
Personal versions of WPA/WPA2, also know as WPA/WPA-PSK (
Pre-Shared Key
), provides 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
complex and as long as possible. The number of ASCII characters of the Passphrase must be at
least 8 and can go up to 63. For security reason, this passphrase should be disclosed to the relevant
users only and changed regularly.
