Encryption Mode
The possible SX-560 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.
To set the encryption mode, select the desired mode from the pull down menu on the Configure Network
Security screen in the SX-560 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
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 SX-560 internal web pages, or use the console command SET NW KEY#
n , where
n is 1, 2, 3, or 4.
WEP Key Value
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 SX-560 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
If you are using WPA2 or WPA with the PSK mode of authentication, the key value or passphrase
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. A passphrase must be 8 to 63 displayable characters. Enter the desired PSK
on the Configure Network Security screen in the SX-560 internal web pages, or use the console
command SET NW WPAPSK <psk>, where <psk> is the key.
Wireless Authentication Type
This parameter sets the type of authentication to be performed with the network access point (Radius
authentication server), or with a peer unit in Ad Hoc mode. The SX-560 supports Shared Key and Open
System Authentication with WEP, and PSK, TLS, TTLS, LEAP, PEAP, and EAP-FAST with WPA, WPA2,
DYNAMIC WEP, and WPA2-WPA. ). Select the desired wireless authentication type on the Configure
Network Security screen in the SX-560 internal web pages, or use the console command SET NW
AUTHTYPE <type>, where <type> is OPEN, SHARED, TTLS, PEAP, WPA-PSK, LEAP, TLS, or EAP-FAST.
User ID
This parameter is the logon user ID that the SX-560 uses to authenticate to the 802.1x-enabled network.
The user ID and password must be in the authentication server database. The default user ID is
'anonymous'. Enter the user ID on the Configure Network Security screen in the SX-560 internal web
pages, or use the console command SET NW ID <user id>, where <user id> is the user ID (the realm can
included in the user id with the separator “@”).
