摘要：The most promising rapid advancements and thedistinct features of MANETs resulted into its predominantusage. With its increased usage, intentional inference attacksreferred to as jamming attacks are also being increasedmainly due to its open nature. Jammers are of many types ofwhich Reactive Jammer is the most malicious one. Reactivejammer initiates jamming activity only when it senses anytransmission on a certain channel in the adhoc networks. As aresult, a reactive jammer targets on compromising thereception of a message. It can interrupt the transmission ofboth small and large sized packets. Since reactive type ofjammer does not constantly monitor the network, it is lessenergy efficient than the other types of jammers. These typesof jammers can cause massive damage to the communicationsystem by corrupting the data that is being sent whicheventually leads to jam in the network. We have addressed theproblem by adopting an effective hiding scheme. Our hidingmechanism is the combination of a commitment scheme, acryptographic puzzle and an authentication mechanism.Commitment scheme is used to generate cipher text alongwith a committed value. A cryptographic puzzle is chosen tohide the committed value and authentication of the receiver isverified to send the hidden committed value. We analyze thesecurity of our method and evaluate their computational andcommunication overhead.
