Silex technology SX-500-1402 manual Encryption Mode Wireless Security Only

you would need to enter a User ID and Password, an Authentication Certificate, and a Private Key with corresponding public key certificate..

The following is a description of the authentication settings used by the Serial Device Server:

Encryption Mode (Wireless Security Only)

The possible Serial Device Server wireless encryption modes include:

∙64 and 128 bit WEP. These are available for basic WIFI compatibility. Because of known security issues, WEP should be avoided if possible.

∙Dynamic WEP. Dynamic WEP uses WEP encryption with an 802.1X EAP authentication method. It is not necessary to set keys with this method, because they are automatically assigned.

∙WPA2. WPA2 is the latest and strongest wireless security standard. It uses CCMP encryption. Like WPA, it can be used either with a pre-shared key or with 802.1X authentication.

∙Wi-Fi Protected Access (WPA). WPA uses TKIP encryption, and can be used with either a pre- shared key (PSK) or with 802.1X authentication.

∙WPA2-WPA. This mode combines the capabilities of WPA2 and WPA by using CCMP for pairwise encryption, but allowing TKIP for group encryption.

NOTE: FIPS 140-2 approved operation requires WPA2 (AES-CCMP) encryption

To set the encryption mode, select the desired mode from the pull down menu on the Configure Network Security screen in the Serial Device Server internal web pages, or use the console command SET NW ENC <mode>, where <mode> is DISABLE, 64, 128, WPA, OR WPA2.

Note that the encryption mode only applies to wireless networks, so it is not necessary to set this mode if you are using a wired Ethernet network.

Key Selection (Wireless Security Only)

This parameter selects which of the four possible WEP keys will be used as the transmit key (the first key is the default). Select the desired key selection from the pull down menu on the Configure Network Security screen in the Serial Device Server internal web pages, or use the console command SET NW KEY# n, where n is 1, 2, 3, or 4.

WEP Key Value (Wireless Security Only)

Up to four keys can be entered if you are using WEP security. The value of the keys must be entered as hexadecimal digits (up to 10 hex digits for 64 bit WEP or 26 hex digits for 128 bit WEP). Enter the desired key value(s) on the Configure Network Security screen in the Serial Device Server internal web pages, or use the console command SET NW KEYVAL <key>, where <key> is 10 hex digits for WEP64 or 26 hex digits for WEP128.

Pre-Shared Key (Wireless Security Only)

If you are using WPA2 or WPA with the PSK mode of authentication, the key value entered here is used to initialize the session with the access point. If a key value is entered, it must be exactly 64 hex characters. Enter the desired PSK on the Configure Network Security screen in the Serial Device Server internal web pages, or use the console command SET NW WPAPSK <psk>, where <psk> is the key.

WPA Group Key (Wireless Security Only)

If the WPA Group Key mode is enabled, then group keys may be used for data link encryption (the default is disabled). Select whether to enable or disable the WPA Group Key on the Configure Network Security screen in the Serial Device Server internal web pages, or use the console command SET NW WPAGROUP <state>, where <state> is ENABLED or DISABLED.

NOTE: For FIPS 140-2 approved operation, this parameter must be DISABLED.
