Toward a Sensor Trustworthiness Measure for Grid-Connected IoT-Enabled Smart Cities

Traditional security measures for large-scale critical infrastructure systems have focused on keeping adversaries out of the system. As the internet of things (IoT) extends into millions of homes, with tens or hundreds of devices each, the threat landscape is complicated. IoT devices have unknown access capabilities with unknown reach into other systems. This paper presents ongoing work on how techniques in sensor verification and cyber-physical modeling and analysis on bulk power systems can be applied to identify malevolent IoT devices and secure smart and connected communities against the most impactful threats.
