Collaborative Authentication and Attack Detection Scheme for Mobile Ad Hoc Network

Abstract

In Mobile Ad Hoc Networks (MANETs), a primary requirement for connection establishment to perform a communication among nodes is that nodes should cooperate with each other. In MANET, the presence of malicious node may lead to serious security concerns; for instance, such nodes may disrupt the routing process. In this situation, preventing and detecting malicious nodes which launch gray hole or collaborative black hole attacks is very challenging. This paper attempts to resolve this issue by designing a Dynamic Anonymous Source Routing (DASR)-with effective Collaborative Authentication and Attack Detection scheme (CAAD). The proposed approach integrates the advantages of both proactive and reactive defense architectures. The CAAD method implements an effective tracking technique to find the attacker.
