6.Setting Up WEP Encryption and Authentication
Wired Equivalent Privacy (WEP) encryption and shared authentication provides protect for your
data on the network. WEP uses an encryption key to encrypt data before transmitting it. Only
computers using the same encryption key can access the network or decrypt the encrypted data
transmitted by other computers. Authentication provides an additional validation process from
the adapter to the access point.
Supported authentication schemes are Open and Shared-Key authentication:
• Shared-Key authentication is supported using 64-bit and 128-bit WEP encryption keys.
• Open mode does not use an encryption authentication method to associate to a specific
access point.
Encryption Overview
Security in the WLAN can be achieved by enabling data encryption using WEP (Wireless
Encryption Protocol). You can choose a 64 or 128 bit level encryption. Also, the data can then
be encrypted with a key. Another parameter called the key index is provides the option to create
multiple keys for that profile. However, only one key can be used at a time. You can also
choose to password protect the profile to ensure privacy.
The pass phrase is used to generate a WEP key automatically. You have the option of either
using a pass phrase or entering a WEP key manually. Using 64-bit encryption, the pass phrase
is 5 characters long and you can choose to enter any arbitrary and easy to remember phrase
like Acme1 or enter 10 Hexadecimal numbers for the WEP key corresponding to the network
the user wants to connect to. For 128-bit encryption, the pass phrase is 13 characters long or
you can enter a 26 hexadecimal numbers for the WEP key to get connected to the appropriate
network.
Note: You must use the same encryption type, key index number, and WEP key as other
devices on your wireless network. Also, if 802.1x authentication is being used, WEP encryption
must be disabled.
To enable 64-bit (40-bit) or 128-bit encryption with authentication:
1. Select the wireless adapter in the left-side pane.
2. From the General page, click the Networks tab.
3. Select the profile from the Profile List and click the Edit button or click the Add button if
you are using the Profile Wizard.
4. Click the Security tab. Select Security Settings, the third dialog if using the Profile
Wizard.
5. Select Shared from the Network Authentication drop-down box.
