Reliability of Autonomous Internet of Things Systems With Intrusion Detection Attack-Defense Game Design

In this article we develop an intrusion detection attack–defense game for Internet of Things (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 intrusion detection system (IDS) attack-defense game design greatly improves system reliability over existing autonomous IoT systems without gaming design consideration when attacks are reckless and intensive.
