Keywords: Selective Jamming | Denial-of-Service | Wireless Networks | Packet Classification

In this paper, we address the problem of selective jamming attacks in wireless networks. In theseattacks, the adversary is active only for a short period of time, selectively targeting messages of highimportance. We illustrate the advantages of selective jamming in terms of network performance degradationand adversary effort by presenting two case studies; a selective attack on TCP and one on routing. We showthat selective jamming attacks can be launched by performing real-time packet classification at the physicallayer. To mitigate these attacks, we develop three schemes that prevent real-time packet classification bycombining cryptographic primitives with physical-layer attributes. We analyze the security of our methodsand evaluate their computational and communication overhead.
