10.0 WLAN Security
The Airborne Enterprise Wireless Device Server family supports all the latest WiFi
security interoperability requirements for 802.11 products; this includes WEP, WPA and
WPA2. The Airborne product family supports both Personal and Enterprise versions of
WPA2, allowing delivery and storage of certificates and private keys to the module.
The configuration of the module for each of these security configurations is similar,
utilizing common security commands with parameter variations to identify the method
required. Each method does have supporting information and parameters to be defined,
the following sections identify the typical requirements for these different security type.
It is assumed in all of the following descriptions that a valid Service Set Identifier (SSID)
has been entered into the device server.
10.1 Disabled (No Security)
Under this mode there is no security applied. The only condition of association is
compatibility of the radio with the infrastructure.

A wireless network using this protocol is not secure and is open to attack and intrusion.
Devices and data on such a network should be considered at risk. This configuration is
not recommended for anything other than initial set-up of the device.
10.2 WEP Security
Wired Equivalent Privacy (WEP) was the original security protocol adopted by
802.11. WEP uses the stream cipher RC4 for confidentiality and CRC-32
checksum for message integrity. The standard was compromised in 2004 and
has been depreciated as a security method. Although organizations still utilize
WEP, it is not a recommended as a security protocol.
Standard 64-bit WEP uses a 40 bit key and a 24 bit initialization vector (IV), to
form the RC4 traffic key, this is also known as WEP-40. The 128-bit version of
WEP utilizes the same 24 bit IV but includes a 104 bit key (WEP-104).
The 64 bit and 128 bit keys are entered manually into the device server. These
must match the keys in the target AP.
To configure the module for WEP the following commands must be completed,
note that the full description of the commands and available parameters can be
found in section 14.0:
Table 3 - WEP Configuration Parameters
Command Description
wl-security wep128 Defines WEP with a 128 bit key.
wl-auth auto
Allows the client and AP to decide the most
appropriate authentication type.
