WebWEP Security Flaw Even though cryptanalysis results as presented in the literature indicate certain weaknesses for RC4, the essential WEP security flaws are NOT due to the weakness of RC4. Actually, we will see that the WEP security flaws still exist even though RC4 is replaced with a stronger algorithm. Professor Guang Gong Lecture 6-c/7. WebWEP is the initial security mechanism specified in the original 802.11 standard and was superseded by the 802.11i standard update. The 802.11 standard initially had security flaws that were resolved with the introduction of the 802.11i standard update.

Diving into Wireless Network Threats – Weaknesses in WEP

WebBackground: WPA-TKIP uses WEP's key structure, changing the 104-bit key on every packet using key mixing. The 24-bit IV is however generated from the low 16-bit of a replay counter, which still created keystream biases in RC4. They are however much more difficult to exploit than WEP's keystream biases where the 104-bit key is always the same. WebBottom Line: WEP Security Is Unacceptable All these flaws of WEP are limitations of the basic WEP protocol. Within a few years of introduction of the WEP standard, researchers (see [FLU01] and [ARB02]) produced actual demonstration programs showing the ability to deduce an RC4 key in minutes.
