Abstract

The open environment of the wireless middle leaves it susceptible to intentional interference attacks, normally referred to as blocking. This intended interference with wireless transmissions can be used as a mounting refutation of- Service attacks on wireless networks. Generally blocking has been addressed under an peripheral threat model. Though, adversaries with internal acquaintance of protocol specifications and network secrets can begin small-effort jamming attacks that are difficult to detect and counter. During this work, we address the problem of selective jamming attacks in wireless networks. In these attacks, the challenger is energetic simply for a small phase of time, selectively targeting messages of high importance. We demonstrate the advantages of selective jamming in terms of network performance degradation and challenger effort by presenting two case studies. a selective attack on TCP and one on routing. We show that selective jamming attacks can be launched by performing real-time packet classification at t he physical layer. En route for moderate these attacks, we extend three schemes to prevent existent-point packet organization by combining cryptographic primitives with physical-layer attributes. We analyze the security of our methods and evaluate their computational and communication transparency.
