Select WPA-PSK (or WPA2-PSK, or Mixed WPA/WPA2-PSK) from the Security Mode drop-down list
menu, the following parameters appear. See the following figure.
Parameter description
Parameter
Description
The AP supports the following three encryption algorithms:
AES: Advanced Encryption Standard. This is newer Wi-Fi encryption solution used
by the new-and-secure WPA2 standard. It is more secure than TKIP.
Encryption Algorithm
TKIP: Temporal Key Integrity Protocol. This is an older encryption protocol
introduced with WPA. This option is recommended only when you have older
devices that can’t connect to a WPA2-PSK (AES) network.
AES&TKIP: It indicates that both AES and TKIP are supported.
Key
It indicates the key used for wireless clients to connect to the access point.
Key Update Interval
It indicates the interval at which a WPA key is updated. A shorter interval leads to
higher security.
WPA and WPA2
To address the key management weakness of WPA-PSK and WPA2-PSK, the WiFi Alliance puts
forward WPA and WPA2, which use 802.1x to authenticate devices and generate data encryption–
oriented root keys. WPA and WPA2 use the root keys to replace the pre-shared keys that set
manually, but adopt the same encryption process as WPA-PSK and WPA2-PSK.
WPA and WPA2 uses 802.1x to authenticate devices and the login information of a device is
managed by the device. This effectively reduces the probability of information leakage. In addition,
each time a device connects to an AP that adopts the WPA or WPA2 security mode, the RADIUS
server generates a data encryption key and assigns it to the device, which makes it difficult for
attackers to obtain the key. These features of WPA and WPA2 security modes help increase network
security significantly, making WPA and WPA2 the preferred security modes of WiFi networks that
require high security.
