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 2100E 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 2100E, 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 2100E:

Enable Encryption

Enable Encryption (Y) ? _

Key length in bits (256): _

Change Key (N) ? _

Enter Key: _

Enable Encryption	This option enables AES encryption for tunneling only.
Key length in bits	Valid options are 128, 192 and 256 bits.
Change Key	Select to modify the current AES encryption key. The default is N
	(No).
Enter Key	If you selected Change Key, enter the key (at the Enter Key
	prompt) in hexadecimal numbers. Enter 32 characters for 128 bits
	key length, 48 characters for 192 bits key length, or 64 characters
	for 256 bits key length.

Encryption only applies to the port selected for data tunneling (default 10001), regardless of whether you are using TCP or UDP.

Generally, one of two situations applies:

Encrypted WiBox 2100E-to-WiBox 2100E communication. Be sure to configure both WiBox 2100E devices with the same encryption key.

Third-party application to WiBox 2100E-encrypted communication: WiBox 2100E 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 2100E.

Lantronix Secure Com Port Redirector provides an encrypted connection from Windows- based applications to the WiBox 2100E. Information about SCPR is at http://www.lantronix.com/device-networking/utilities-tools/scpr.html .

A 30-day trial version of SCPR is included on the CD.

Enable Enhanced Password

This setting defaults to the N (No) option, which permits a 4-character password to protect Setup Mode by means of Telnet and web pages.
