Implementation of packet-hiding algorithm for preventing selective jamming attacks

In the network environment most of the time there could be more chances of attacks. That means most of the time it does not guarantee about the packets can be easily transfer over the network. It affects network performance degrade. To overcome the above problem of network traffic and performance implementing a Packet Hiding Scheme that can be securely sent packets over the network. While eavesdropping and message injection can be prevented using cryptographic methods, jamming attacks are much harder to counter. They have been shown to actualize severe Denial-of-Service (DoS) attacks against networks. In the simplest form of jamming, the adversary interferes with the reception of messages by transmitting a continuous jamming signal or several short jamming pulses. Typically, jamming attacks have been considered under an external threat model, in which the jammer is not part of the network. In this paper we are developing and survey on the three schemes that prevent real - time packet classification by combining Cryptographic Puzzles, SHCS, and AONT. We analyze the security of our methods and evaluate their computational and system overhead.
