WLAN Protection Enhancements
So far we have discussed generic solutions and tools. The following section will review specific tools to correct WEP-related vulnerabilities, as well as other security enhancements that are being considered for future versions of 802.11 networks.
The Temporal Key Integrity Protocol (TKIP) is a more recent security feature offered by various vendors to correct the weak WEP problem. It was developed by some of the same researchers who found the weaknesses in how RC4 was implemented. TKIP corrects these weaknesses and more.
This new protocol still uses RC4 as the encryption algorithm, but it removes the weak key problem and forces a new key to be generated every 10,000 packets or 10kb, depending on the source. ...
