Packet Hiding Method for Preventing Jamming Attack in Wireless Network

Wireless network is infrastructure less network. The open nature of the wireless intermediate leaves it open to on purpose interference attacks, typically referred to as jamming. This intentional attacks interference with wireless transmissions can be used as an initiate protection for increasing rejection-of-Service attacks on wireless network system Jamming has been address under an external risk reproduction. However, adversary with internal knowledge of protocol specification and link secrets can initiate low down exertion jamming attacks that are difficult to detect and counter. In this work, we address the problem of careful jamming attack in wireless system. In these attacks, the adversary is active only for a short period time, target communication of high value .We illustrate the compensation of jamming in terms of network performance degradation and opponent effort by the presenting two case study. a discerning attack on TCP and one on routing. We demonstrate that the selective jamming attacks can be launch by the stage real time small package classification of the physical layer. To take the frame off these attacks, we develop three schemes that the put off real time packet arrangement by combine cryptographic primitive with the objective-level attribute. We investigate the security of our methods and estimate their computational and communication visual projection.
