Game based DDoS Attack Strategies in Cloud of Things

Integration of Internet of Things (IoT) with Cloud Computing, termed as Cloud of Things (CoT). In typical CoT infrastructure, the data collected from wireless sensor networks and IoTs will be transmitted through smart gateway (SG) to cloud. The bandwidth between IoT access point and SG becomes a bottleneck for information transmission. In this paper, we propose a novel game-theory model to describe the CoT attacker, who expects to use minimum set of IoT attack devices to occupy as much bandwidth resources as possible in a given time. By analyzing the model, we have found that the game model is a non-cooperative and repeated games of incomplete information. The best strategy for the attacker is that if over the half of attack connections are effective, decreasing number of attack nodes; contrary, increasing number of attack nodes. The simulation result shows that our strategy can decrease the number of exposed attack devices for the Distributed Denial of Service(DDoS) attack significantly.
