Setting WEP Modes And Keys On The 802.11b Radio Card
This section describes how to set WEP (Wired Equivalent Privacy) modes and keys on
the Cisco® 802.11b radio card.
WEP is used to encrypt and decrypt data signals transmitted between Wireless LAN
(WLAN) devices. WEP is an optional IEEE 802.11 feature used to provide data
confidentiality that is equivalent to the confidentiality of a wired LAN that does not
employ crypto techniques to enhance privacy. WEP makes a wireless LAN link as
secure as a wired link.
The wep.bat utility is used to set WEP modes and keys for the Cisco® 802.11b radio
card. The wep.bat file uses three files:
wepdos.exe – an executable file that configures WEP values for the Cisco radio
keys.exe – an executable file that calls the functions for setting WEP values
cscpkt.ini – a configuration file for the Cisco radio
All four files are located in the Dolphin c:\rf directory that is part of the
stackcsc.exe file.
If the user will be setting WEP keys using the batch mode, the user must create a
keys.txt file using a text editor such as Notepad and then copy it to the c:\rf directory.
This file will contain the encryption keys used when operating in WEP mode. For
obvious security reasons, this file will be automatically deleted upon running the
wep.bat utility. HHP recommends that you verify that the keys.txt file has been
deleted.
Refer to the Cisco documentation for complete descriptions of the various WEP
modes. The current radio card may not support some modes.
