Wireless Network Security

Wired Equivalent Privacy (WEP) is the protocol used in wireless networks communications to encrypt data "on air". Without it anyone could just stand with a sniffer and receive everything running in the air.

Introduction on WEP security

As we covered in the Wep Security article , Wep is really an unsafe method of securing a wireless network. What makes wep really unsafe is the 32 bit ICV being static for each frame. This opens a wide variety of techniques to be used to crack a wep key. In this article we will try to understand how the most spread wep cracking tools work and in the end we will review them giving some practical ideas of how successfull they can be.
