AWK-5222 User’s Manual Other Console Configurations

3-17

The AWK-5222 provides four standardized wireless security modes: Open, WEP (Wired

Equivalent Privacy), WPA (Wi-Fi Protected Access) and WPA2. Several types of security models

are available in AWK-5222 by selecting Security mode and WPA type:

y Open: No authentication, no data encryption.

y WEP: Static WEP (Wired Equivalent Privacy) keys must be manually configured.

y WPA/WPA2-Personal: also known as WPA/WPA2-PSK. You need to specify the Pre-Shared

Key in the Passphrase field, which will be used by the TKIP or AES engine as a master key to

generate keys that actually encrypt outgoing packets and decrypt incoming packets.

y WPA/WPA2-Enterprise: also called WPA/WPA2-EAP (Extensible Authentication Protocol).

In addition to device-based authentication, WPA/WPA2-Enterprise enables user-based

authentication via IEEE802.1X. The AWK-5222 can support three EAP methods: EAP-TLS,

EAP-TTLS, and EAP-PEAP.

Security mode

Setting Description Factory Default

Open No authentication

WEP Static WEP is used

WPA WPA is used

WPA2 Fully supports IEEE802.11i with

“TKIP/AES + 802.1X”

Open

For security reasons, it is highly recommended that the security mode should be set to the options

other than Open System. When the security mode is set to Open System, no authentication or data

encryption will be performed.

WEP

According to the IEEE802.11 standard, WEP can be used for authentication and data encryption

(confidentiality). Shared (or Shared Key) authentication type is used if WEP authentication and

data encryption are both needed. Normally, Open (or Open System) authentication type is often

used when WEP data encryption is run with authentication.

When WEP is enabled as a security mode, the length of a key (so-called WEP seed) can be

1 2 ... 30 31 32 33 34 35 36 37 38 39 40 ... 99 100
