Great, here goes:  

ARQ Security for Wi-Fi Networks

Building on our earlier work on Automatic Repeat reQuest (ARQ) information theoretic secrecy, we present the design and evaluation of a simple, yet efficient, overlay security framework to existing 802.11 networks. By exploiting the ARQ mechanism adopted in the 802.11 standards, the proposed

framework aims at enhancing the security of three Wi-Fi security protocols, namely, WEP, TKIP and CCMP, in infrastructure networks, via only minor modifications over the current standards. Using our implementation on the Madwifi driver, our experimental results reveal the ability of the proposed ARQ framework to defend against all of the currently known attacks for the aforementioned protocols, at the expense of a larger link setup time and a marginal loss in throughput over the baseline implementations of the standard protocols.
