摘要：The Open Nature of wireless medium leaves an intentional interference attack, typically referred to asjamming. This intentional interference with wireless transmission launch pad for mounting Denial-Of-Service attack onwireless networks. Typically, jamming has been addresses under an external threat model. However, adversaries withinternal knowledge of protocol specification and network secrets can launch low-effort jamming attacks that aredifficult to detect and counter. In this work we address the problem of jamming attacks and adversary is active for shortperiod of time, selectively targeting the messages of high importance. We show that the selective jamming attacks canbe launched by performing real-time packet classification at the physical layer. To mitigate these attacks, we developthree schemes that prevent real-time packet classification by combining cryptographic primitives with physical-layerattributes. They are Strong Hiding Commitment Schemes (SHCS), Cryptographic Puzzles Hiding Schemes (CPHS),All-Or-Nothing Transformation Hiding Schemes (AONTS-HS). Random key distribution methods are done along withthree schemes to give more secured packet transmission in wireless networks
