8. Security and Authentication Modes
The current release of Wifly firmware supports these security modes:
• WEP-128 (open mode only, NOT shared mode )
• WPA2-PSK (AES only)
• WPA1-PSK (TKIP only) this requires special firmware.
For WEP-128, shared mode is not supported as it is know to be quite easily
compromised, and has been deprecated from the WiFi standards.
Roving Networks discourages the use of WPA1-PSK as it has been proven that mode can
be compromised easily. Other modes, such as WPA-PSK mixed mode, and WPAenterprise
are not yet supported, but may be offered in future releases. Contact Roving
Networks if you wish to discuss potential future support of other modes.
Listed below are the commands used to set authentication.
set wlan auth <value> sets the authentication level. 0= Open mode, 2=WPA2-PSK
(AES only supported) , 3=WEP-128.
set wlan key <num> <value> sets the WEP key. key must be EXACTLY 13 bytes (26
ASCII chars). Data is expected in HEX format, “0x” should NOT be used here.
Example : “set w k 112233445566778899AABBCCDD”
Hex digits > 9 can be either upper or lower case.
set wlan phrase <string> sets the passphrase for WPA security modes. 1-64 chars.
The passphrase can be alpha and numeric, and is used along with the ssid to generate a
unique 32 byte Pre-shared key (PSK), which is then hashed into a 256 bit number.
Example : “set w p password” sets the phrase.
DIRECT PSK entry mode: If exactly 64 chars are entered, it is assumed that this entry
is already an ASCII HEX representation of the 32 byte PSK and no processing is done.
Example : “set w p 0123456789…..AABBCCDD”
