7.2 Security Parameters Summary

Refer to this table to see what other security parameters you should configure for each
Authentication Method/ key management protocol type. You enter manual keys by first
selecting 64-bit WEP or 128-bit WEP from the WEP Encryption field and then typing the
keys (in ASCII or hexadecimal format) in the key text boxes. MAC address filters are not
dependent on how you configure these security features.

7.3 WEP Overview

WEP (Wired Equivalent Privacy) as specified in the IEEE 802.11 standard provides methods
for both data encryption and wireless station authentication.

7.3.1 Data Encryption

WEP provides a mechanism for encrypting data using encryption keys. Both the AP and the
wireless stations must use the same WEP key to encrypt and decrypt data. Your ZyAIR allows
you to configure up to four 64-bit or 128-bit WEP keys, but only one key can be enabled at
any one time.

7.3.1.1 Authentication

Three different methods can be used to authenticate wireless stations to the network: Open
System, Shared Key, and Auto. The following figure illustrates the steps involved.
