Reliability of Autonomous IoT Systems with Intrusion Detection Attack-Defense Game Design

In this paper we develop an intrusion detection attack-defense game for IoT systems for which autonomous IoT devices collaboratively solve a problem. We develop an analytical model to determine the conditions under which malicious nodes have no incentives to perform attack in the intrusion detection attack-defense game. We also develop a stochastic Petri net model to analyze the effect of attack-defense behaviors on system reliability, given a definition of system failure conditions as input. The performance evaluation results demonstrate that our IDS attack-defense game design greatly improves system reliability over existing autonomous IoT systems without gaming design consideration when attacks are reckless and intensive.
