Overview of WEP Parameters

Before enabling WEP on an 802.11 network, you must first consider what type of encryption you

require and the key size you want to use. Typically, there are three WEP Encryption options

available for 802.11 products:

1. Do Not Use WEP: The 802.11 network does not encrypt data. For authentication purposes, the

network uses Open System Authentication.

2. Use WEP for Encryption: A transmitting 802.11 device encrypts the data portion of every

packet it sends using a configured WEP Key. The receiving device decrypts the data using the

same WEP Key. For authentication purposes, the network uses Open System Authentication.

3. Use WEP for Authentication and Encryption: A transmitting 802.11 device encrypts the data

portion of every packet it sends using a configured WEP Key. The receiving device decrypts the

data using the same WEP Key. For authentication purposes, the wireless network uses Shared Key

Authentication.

Note: Some 802.11 access points also support Use WEP for Authentication Only (Shared Key

Authentication without data encryption).
