Simulation study of routing attacks under network coding environment

Network coding has been introduced as a new paradigm for network routing protocols in recent years. The wide range of advantages of network coding, such as energy saving, throughput improvement and congestion mitigation, have been demonstrated in many practical systems. However, the nature of packet mixing, optimization of forwarding nodes selection cause the network coding based routing protocols vulnerable to routing attacks. In this paper, we conduct a detailed analysis of various security threats that attack on different components of intra-flow network coding based routing schemes, and provide an extensive simulation study of their impacts on the network performance. An adequate understanding of both threats and vulnerabilities of current network coding systems are essential to effectively design of defense mechanism. This paper is served as a preliminary guide in the effort of achieving security for network coding based wireless routing.
