34 DL-WINDOWS™ for Trilogy Networx™ V4.0 USER'S GUIDE

Channel Number

Click this pull-down menu to manually specify the number (1-

11) of the carrier frequency (subchannel pathway) between

the selected Gateway and the wireless Wi-Fi (802.11)

network. Contact your network administrator for more

information.

For the selected Gateway, click the pull-down menu to

specify the 802.11 security protocol (encryption method) to

be used when the selected Gateway is connected to the

wireless network. The selections are as follows:

WEP (Wired Equivalent Privacy) The WEP encryption

method was designed to provide wireless networks with the

"equivalent" security available in traditional wired "landline"

networks.

WPA (Wi-Fi Protected Access) A security protocol from the

Wi-Fi alliance for 802.11 wireless networks. It uses the

Temporal Key Integrity Protocol (TKIP) to provide stronger

encryption than the earlier WEP (Wired Equivalent Privacy)

method. Derived from, and a subset of, the IEEE 802.11i

security standard, WPA includes 802.1x authentication.

WPA2 Supports additional security features of the IEEE

802.11i standard that are not already included in the WPA

security protocol.

Note: For each Security Type selected, different choices

appear for the other fields in the Wireless Network Security

area of this screen.

Verifies the origin of transmitted data.

For the selected Gateway, click the pull-down menu to

specify the 802.11 authentication protocol to be used when

the selected Gateway is connected to the wireless network.

When WEP Security Type is selected, the options for the

selected Gateway are:

● Open/None: Requires no Authentication for the data

transmissions between the selected Gateway and DL-

Windows.

● Shared: Requires a shared symmetric numeric code

(encryption "key") for all data transmissions between DL-

Windows and the Gateway.

When WPA or WPA2 Security Type is selected, the option

is:

● Pre-Shared Key (PSK): Requires a numeric code

(encryption "key") previously shared between DL-

Windows and the Gateway using a secure channel for

all data transmissions.

A "key" is a numeric code used to encrypt data, and is used

to secure the data traffic between the DL-Windows, the

Gateways and the locks. The key "type" can be a pass-

word, a passphrase, or a hexadecimal string like '45D3

E454 3523 EDC2'. To ease encryption key entry, a pass-

word or passphrase can be entered instead of the cryptic

hexadecimal characters.

The reversible transformation of data from its original for-

mat into a concealed format as a process for securing its

accessibility, authenticity and integrity. Encryption uses an

encryption algorithm (sequence) and one or more encryp-

tion keys (numeric codes).

When WEP Security Type is selected, the options for the

selected Gateway are:

● 64 bits: Although the 64-bit WEP data encryption

method uses a five-character key size (forty bits or five

bytes) for symmetric encryption, plus an additional 24

factory-set bits, this method represents a relatively low

level of security.

● 128 bits: Stronger than 64-bit WEP, 128-bit WEP uses

a string of 26 hexadecimal characters (0-9 and A-F),

each representing four bits of the key.

When WPA Security Type is selected, the option for the

selected Gateway is:

● TKIP: (Temporal Key Integrity Protocol), a security pro-

tocol algorithm that compliments WEP encryption with

increased security measures such as extended key

lengths and data integrity checks.

When WPA2 Security Type is selected, the options for the

selected Gateway are:

● CCMP: (Counter Mode with Cipher Block Chaining

Message Authentication Code Protocol) improves upon

both WEP and TKIP. CCMP is a required option for Ro-

bust Security Network (RSN) compliant networks.

● TKIP: See above.

Retype Key

Type your key in the Key field, and re-type in the Retype

Key field to confirm it.

Retrieves the current settings of the Gateway and displays

these settings in this screen.

Click Save Configuration to save your settings and close

the screen, or click Close to exit without saving.
