In order to configure standard 40-bit WEP, you must have two or more radio units that communicate with each other. This document assumes that you can make an administrative connection to the WLAN devices and that the devices function normally in an unencrypted environment. TKIP uses RC4 stream cipher with 128-bit keys for encryption and 64-bit keys for authentication. However, TKIP enhances WEP by adding measures such as per-packet key hashing, Message Integrity Check (MIC), and Broadcast key rotation to address known vulnerabilities of WEP. Similar to WEP, TKIP uses RC4 encryption. Temporal Key Integrity Protocol (TKIP) has been created to address these WEP issues. The WEP checksum is linear and predictable. The IV that seeds the WEP algorithm is sent in clear text. Any secret given to one person becomes public after a period of time. WEP has the same problem as all systems based on shared keys. There is a great deal of administrative overhead to maintain a shared WEP key. Note:В There are some known issues with WEP, which makes it not a strong encryption method. Therefore, minimal performance impact results when you use WEP. WEP can be primarily used for a home office or a small office that does not require very strong security.ДЄironet WEP implementation is in the hardware. If a station receives a packet that is not scrambled with the appropriate key, the packet is discarded and never delivered to the host. The key is used to scramble the data before transmission of the data through the airwaves. When WEP is enabled, each radio 'station' has a key. RC4 is a symmetric algorithm because it uses the same key for the encryption and the decryption of data.

WEP encryption uses the Ron's Code 4 (RC4) Stream Cipher with 40- or 104-bit keys and a 24-bit initialization vector (IV).ДЄs the standard specifies, WEP uses the RC4 algorithm with a 40-bit or 104-bit key and a 24-bit IV. WEP is the encryption algorithm built into the 802.11 (Wi-Fi) standard. Note:В Refer to the Static Web Keys section of Chapter 6 - Configuring WLANs for more information on WEP configuration on wireless LAN controllers (WLCs). This document provides methods to configure Wired Equivalent Privacy (WEP) on Cisco Aironet Wireless LAN (WLAN) components.
