Adjustable security for RFID-equipped IoT devices

Abstract

Over the last years, the number of rather simple interconnected devices in nonindustrial scenarios (e.g., for home automation) has steadily increased. For ease of use, the overall system security is often neglected. Before the Internet of Things (IoT) reaches the same distribution rate and impact in industrial applications, where security is crucial for success, solutions that combine usability, scalability, and security are required. We develop such a security system, mainly targeting sensor modules equipped with Radio Frequency IDentification (RFID) tags which we leverage to increase the security level. More specifically, we consider a network based on Message Queue Telemetry Transport (MQTT) which is a widely adopted protocol for the IoT.
