The Open Nature of wireless medium leaves an intentional interference attack, typically referred to as jamming. This intentional interference with wireless transmission launch pad for mounting Denial-Of- Service attack on wireless networks. Typically, jamming has been addressed under an external threat model. In this work, we address the problem of jamming attacks and adversary is active for short period of time, selectively targeting the messages of high importance. We show that the 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. They are Strong Hiding Commitment Schemes (SHCS), Cryptographic Puzzles Hiding Schemes (CPHS), and All- Or-Nothing Transformation Hiding Schemes (AONTSHS).

Keywords: cryptographic, jamming, Denial-of-Service(DoS)
