Wireless reconfigurable networks are prone to several security attacks such as selective forwarding, black holes, and wormholes. In this paper, we introduce a network coding method that detects security attacks related to routing. The proposed method works on a distributed fashion performing random network coding over 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 responseunder security attacks for varying network conditions, such as density and interference, and it also increases successfully received packets without a significant sacrifice of the bandwidth usage.
