Packet Classification Method for Preventing Selective Jamming Attacks

In this book we address the problem of selective jamming attacks in wireless networks. In these attacks the adversary is active only for a short period of time selectively targeting messages of high importance. This work illustrated the advantages of selective jamming in terms of network performance degradation and adversary effort by presenting two case studies; a selective attack on TCP and one on routing. This work proves that selective jamming attacks can be launched by performing real-time packet classification at the physical layer. To mitigate these attacks we develop three schemes that prevent real-time packet classification by combining cryptographic primitives with physical-layer attributes. This work analyzes the security of our methods and evaluate their computational and communication overhead.
