Chapter 4: XPress DR+W

Point to many wireless devices at once is called multicast and uses the group encryption method.

To receive broadcast and multicast messages, the group encryption for all wireless devices communicating with the same access point must be equal. If any of these devices is WEP-only (no support for WPA), set the encryption to TKIP+WEP.

A group encryption lower than the pairwise encryption is necessary to use higher security with the XPress DR+W than other devices connecting to the same Access Point can support.

CCMP is also called AES on products of other manufacturers. CCMP is an extension of AES. It provides the strongest current encryption method.

WEP

Authentication selects whether the encryption keys are matched (1 = shared) with those of the communication partner before passing through messages or not (2 = open/none).

The Encryption prompt requests the length of the encryption key and the security strength. WEP64 uses a 40 bits/5 bytes key (option 1). WPE128 uses a 104 bits/13 bytes key (option 2).

Select Y (Yes) at the Display current key prompt to show the currently configured key/passphrase.

Select Y (Yes) at the Change key prompt to be able to modify the currently configured key.

The Key type indicates whether the new key is in hexadecimal or passphrase format.

Enter key prompts for the new encryption key.

Key Type	Encryption Key
Hex	Enter the Encryption Key as a hexadecimal value according the following
	guidelines:
	 Valid Hex alphanumeric characters are 0-9 and A-F.
	 64 bit hex = 5 bytes represented as xx-xx-xx-xx-xx.
	Example: 01-A3-47-E5-C9
	 128 bit hex = 13 bytes represented as xx-xx-xx-xx-xx-xx-xx-
	xx-xx-xx-xx-xx-xx.
	Example: A1-B2-C3-E4-D5-F6-98-74-B7-65-A8-D3-F2
Passphrase	Enter the key as a string. A passphrase is a sentence that is translated into
	hex by a hashing algorithm.
	Example: My dog has spots and likes to chase cats.
	A passphrase of more than 20 characters is recommended. Maximum length
	is 63 characters. Spaces and punctuation characters are permitted.
