Security Mode — Configures the WPA-PSK and WPA2-PSK security modes used by
clients. When using WPA-PSK or WPA2-PSK, be sure to define the shared key for
the 3G Mobile Wireless Router and all its clients. (Default: Disable)
WPA-PSK — Clients using WPA with a Pre-shared Key are accepted for
◆
authentication. The default data encryption type for WPA is TKIP.
WPA2-PSK — Clients using WPA2 with a Pre-shared Key are accepted for
◆
authentication. The default data encryption type for WPA is AES.
WPA-PSK_WPA2-PSK — Clients using WPA or WPA2 with a Preshared
◆
Key are accepted for authentication. The default data encryption type is
◆
TKIP/AES. WPA Algorithms — Selects the data encryption type to use. (Default is
determined by the Security Mode selected.)
TKIP — Uses Temporal Key Integrity Protocol (TKIP) keys for encryption. WPA
■
specifies TKIP as the data encryption method to replace WEP. TKIP avoids the
problems of WEP static keys by dynamically changing data encryption keys.
AES — Uses Advanced Encryption Standard (AES) keys for encryption. WPA2
■
uses AES Counter-Mode encryption with Cipher Block Chaining Message
Authentication Code (CBC-MAC) for message integrity. The AES Counter-
Mode/CBCMAC Protocol (AESCCMP) provides extremely robust data confidentiality
using a 128- bit key. Use of AES-CCMP encryption is specified as a standard
requirement for WPA2. Before implementing WPA2 in the network, be sure client
devices are upgraded to WPA2-compliant hardware.
TKIP/AES — Uses either TKIP or AES keys for encryption. WPA and
■
WPA2 mixed modes allow both WPA and WPA2 clients to associate to a common
SSID. In mixed mode, the unicast encryption type (TKIP or AES) is negotiated
for each client.
