Configuration via Serial Mode or Telnet Port
WiBox™ User Guide 71
This setting defaults to the N (No) option, which permits a 4-character password
protecting Setup Mode by means of Telnet and web pages.
Enable Enhanced Password (Y) ? _
The Y (Yes) option allows an extended security password of 16-characters for
protecting Telnet access.
Enable Encryption
Rijndael is the block cipher algorithm chosen by the National Institute of Science and
Technology (NIST) as the Advanced Encryption Standard (AES) to be used by the
US government. The WiBox supports 128-, 192-, and 256-bit encryption key lengths.
Note: Configuring encryption should be done through a local connection to
the serial port of the WiBox, or via a secured network connection. Initial
configuration information including the encryption key is sent in clear text
over the network.
To configure AES encryption on the WiBox:
Figure 8-2. Encryption Keys
1. When prompted to enable encryption, select Y.
2. Enter the encryption key length when prompted. The WiBox supports 128-, 192-,
and 256-bit encryption key lengths.
3. When prompted to change keys, select Y.
4. At the Enter Keys prompt, enter your encryption key. The encryption keys are
entered in hexadecimal. The hexadecimal values are echoed as asterisks to
prevent onlookers from seeing the key. Hexadecimal values are 0-9 and A-F.
 For a 128-bit key length, enter 32 hexadecimal characters.
 For a 192-bit key length, enter 48 hexadecimal characters.
 For a 256-bit key length, enter 64 hexadecimal characters
5. Continue pressing Enter until you return to the Change Setup menu.
6. From the Change Setup menu, select option 9 to save and exit.
Encryption only applies to the port selected for data tunneling (default 10001),
regardless of whether you are using TCP or UDP.
Generally, one of three situations applies:
 Encrypted WiBox-to-WiBox communication. Be sure to configure both WiBox
devices with the same encryption key.
 Third-party application to WiBox-encrypted communication: WiBox uses
standard AES encryption protocols. To communicate successfully, products
and applications on the peer side must use the same protocols and the same
encryption key as the WiBox.
