10.3 WPA Security
WiFi Protected Access (WPA) is a compatibility certification program created by
the WiFi Alliance to indicate compliance to a minimum set of security and
functional capabilities for 802.11 devices. The WPA certification program was
created to mitigate the issues created by the devaluation of the WEP security
standard.
WPA utilizes part of the 802.11i security standard but relies upon the same RC4
cipher as WEP. WPA introduced Temporal Key Interchange Protocol (TKIP) to
802.11 security and this significantly mitigated the flaws that existed in WEP. It
not only hid the key more securely but provided packet sequencing and Message
Integrity Checking (Michael MIC).
The module supports both WPA Personal and WPA-LEAP, the following tables
identify the settings required for configuration of these security methods.
Table 12 - WPA-Personal (PSK) Configuration
Command Description
wl-security wpa-psk Defines WPA with a Preshared Key (PSK).
pw-wpa-psk password
Defines the preshared key used by the module
and must match the same PSK passphrase
used by the AP.
Must be 8-63 ASCII characters long and cannot
include spaces.
Table 13 - WPA-LEAP Configuration
Command Description
wl-security wpa-leap
Defines WPA with EAP-LEAP authentication.
This requires the use of a RADIUS server on
the target network; the server must support
the LEAP authentication process.
user-leap MyUserName
Defines the username to be used for
authentication with the RADIUS server. There
must be a valid user account with the defined
name.
pw-leap MyUserPassword
Defines the password for the user name
defined by user-leap. This must match the
password on the RADIUS authentication server.
10.4 WPA2 Security
WiFi Protected Access 2 (WPA2) is a compatibility certification program created
by the WiFi Alliance to indicate compliance to a minimum set of security and
functional capabilities for 802.11 devices. The WPA2 certification program was
created to enhance the security provided by WPA and utilize more fully the IEEE
802.11i standard and the available advanced hardware.
