Secure Multicast Routing Protocol against Insider Attacks in MANET

Ad-hoc networks are a collection of mobile hosts that communicate with each other without any infrastructure. These networks are vulnerable against many types of insider attacks including black hole attacks and selective data forwarding. Even if many previous works focused on authentication and cryptography techniques, nevertheless these techniques suffer from some weakness. We propose a novel secure multicast routing protocol designed to withstand insider attacks from colluding adversaries. Our protocol is a software-based solution and does not require additional or specialized hardware. We present simulation results that demonstrate that the proposed protocol effectively mitigates the identified insider attacks.
