Securing Cyber-Physical and IoT Systems in Smart Living Environments


Our daily lives are becoming increasingly dependent on smart cyber-physical infrastructures, such as smart homes and cities, smart grid, smart transportation, smart healthcare, smart agriculture, and so on. The wide availability of sensor enabled IoT devices and smartphones are also empowering us with fine-grained data collection and opinion gathering via mobile crowdsensing about events of interest, resulting in actionable inferences and decisions. This synergy has led to cyber-physical-human (CPH) convergence in smart living environments, the goal of which is to improve the quality of life. However, CPH and IoT systems are extremely vulnerable to security threats owing to their interdependence, scale, heterogeneity, human behavior, and trust issues. This talk will highlight unique security challenges in smart living environments, build a unified data falsification threat (anomaly detection) landscape for CPH and IoT systems, and propose novel defense mechanisms for securing such systems. Our solutions are based on a rich set of theoretical and practical design principles, including AI/ML, data analytics, sensor fusion, uncertainty reasoning, information theory, prospect theory, and reputation/belief models. Case studies with real-world datasets will be presented to defend smart grid, smart transportation and smart water distribution networks. The talk will be concluded with future research directions.
