WEP is designed to provide the same level of security for wireless 

LANs as that of a wired LAN. To use WEP encryption, identify the level 

of encryption (64 or 128). If using 64-bit WEP, you will need to program 

the Default WEP key on the AP and each wireless device and designate 

the four alternate 64-bit WEP keys. The four WEP keys thus programmed 

have to be input to the setup utility on each wireless device that will be 

part of the WLAN.

If using 128-bit WEP, simply designate the 48 hexidecimal digits on 

the AP and program the same number on each wireless device. 

Key management becomes increasingly difficult as the number of 

clients increases, but the use of WEP encryption on small office wireless 

networks provides some measure of security. WEP was never intended to 

be a complete security solution but rather provides protection equivalent 

to that of wired networks. 

WPA (non-FIPS)

Wi-Fi Protected Access or WPA was designed to enable use of wire-

less legacy systems employing WEP while improving security. WPA uses 

improved data encryption through the temporal key integrity protocol 

(TKIP) which scrambles keys using a hashing algorithm and, by adding 

an integrity-checking feature, ensures that the keys haven’t been tam-

pered with. In addition, user authentication is enabled using the exten-

sible authentication protocol (EAP).
