Network Coding Based Security for Routing Attacks in WRN: Frechet Interference and Rayleigh Outage Evaluation

We present a network coding security method capable of detecting several routing attacks in wireless reconfigurable networks. Routing security attacks include selective forwarding, black holes, and wormholes. The proposed method performs linear network coding over intermediate nodes composing a given route, not only to distribute content, but also to provide data confidentiality by cooperation as a mechanism of detection. The method presents a robust, accurate and fast response under security attacks for varying network conditions, such as interference and outage due to channel fading. It also provides a gain in network throughput by increasing the number of successfully received packets without a significant increase of the bandwidth usage.
