Secured Packet Hiding Technique for Packet Jamming Attacks
Journal Title: INTERNATIONAL JOURNAL OF COMPUTER TRENDS & TECHNOLOGY - Year 2013, Vol 6, Issue 1
Abstract
Wireless networks are built upon a shared medium that makes it easy for adversaries to launch jamming-style attacks. Jamming attacks can severely interfere with the normal operation of Networks and, consequently, mechanisms are needed that can cope with jamming attacks. The Denial of Service attacks (DoS), the most widespread attack to the Network requires great concern and resilient mechanisms. Typically, jamming has been addressed under an external threat model. However, adversaries with internal understanding of protocol specifications and network secrets can launch low-effort jamming attacks which get problematic to detect and counter. Existing work proposed selective jamming attacks in wireless networks has some limitations. First limitation is Performance delay in a selective attack on TCP and maybe on routing. During these attacks, the adversary is active just for a brief period of valuable time, selectively targeting messages of high importance. Second limitation includes problem in real time packet classification. Proposed model evaluates robust selective jamming attacks detection mechanism while 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. We analyze the security of our methods and evaluate their computational and communication overhead.
