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.
