Packet Hiding Methods for MANET Routing Attacks

Abstract: Mobile ad hoc networks (MANETs) have been highly susceptible due to the flexibility provided by their dynamic infrastructure. The routing attacks could cause severe damage to MANET. Although there are several intrusion response techniques to alleviate such critical attacks, existing solutions normally attempt to isolate malicious nodes based on binary or naı¨ve fuzzy response decisions. Though, binary responses may effect in the unpredicted network partition, producing extra damages to the network communication. However, this flexibility introduces new security threats such as routing attacks, Denial-of-Service and selective jamming attacks. Many existing security solutions for conventional networks are ineffective and inefficient for many predicted MANET deployment environments. In our project, we address the problem of routing attacks, Denial-of-Service and selective jamming attacks in mobile ad hoc networks. Therefore, we propose that these MANET routing attacks can be introduced by the real-time packet classification. In such attacks, the rival remains active only for a short span, selectively aiming at highly significant messages. We exemplify the benefits of selective jamming in terms of rival effort and network performance degradation with a selective jamming attack on TCP and another on routing. We explain that selective jamming attacks can be introduced by the real-time packet classification. To alleviate these attacks, we build up schemes that evade real-time packet classification by merging cryptographic primitives. We evaluate the security of our techniques and compute their computational and communication overhead.
