3 To enable encryption on a SPEEDLAN 9200, choose AES from the Encryption
Type drop-down list. "None" is selected by default. (If you select None,
encryption is disabled.) Click Apply to implement your settings.
B. Enabling WEP Security Between a SPEEDMesh-Enabled Client
and SPEEDLAN 9200
In a SPEEDLAN 9200 network, you can authenticate a SPEEDMesh-enabled client (PDA
or laptop) with a standard security called Wired Equivalent Privacy (WEP). WEP encrypts
data that is being transmitted over the wireless LAN. WEP protects the wireless links
between clients and SPEEDLAN 9200 routers.
Note: WEP is an encryption scheme used to protect wireless data communications.
WEP uses 64-bit, 128-bit or 152-bit key sizes to provide access control to wireless
network and encryption security for each data transmission. To decode a data
transmission, each point in a network must use an identical 64-bit, 128-bit or 152-bit
key.
To enable WEP security, do the following:
1 If the Network Security Configurations page is not displayed on your screen,
choose Security from the Network menu. On the bottom section of the
Network Security Configurations page, choose WEP from the Encryption
Type drop-down list. "None" is selected by default. (If you select None,
encryption is disabled.)
2 Choose Hexadecimal or ASCII Text from the Key Format drop-down list.
• "Hexadecimal" is a Base-16 numbering system. The means the 16 sequen-
tial numbers are used as a base unit (i.e., "0-9" and "A-F").
• In ASCII text, each numeric, alphabetic or special character is represented
with a 8-bit binary number (i.e., a consecution of eight 0s or 1s).
3 Select Key 1-3 from the Transmit Key drop-down list.
4 Select the length for the Transmit key by choosing either 64 Bits,128 Bits or
152 Bits from the Length drop-down list.
Note: 40-bit WEP and 64-bit WEP are two different names for the same encryption
method. This level of WEP encryption has been called "40-bit" because it uses a 40-bit
secret key along with a 24-bit initialization vector (i.e., 40 + 24 = 64). The same is
true for 104-128 bit and 128-152 bit WEP.
