Security Analysis of IoT Devices: From the system level to the logic level

IoT devices have become more and more widespread and are playing an important role in the evolving digital society. At the same time, IoT nodes are embedded devices that are always online, often making them interesting targets for potential attackers. Since many IoT applications are closely linked to humans, e. g., medical implants, smart appliances and speakers, and (autonomous) cars, it is of crucial importance that they are trusted to provide safety. Trust in embedded devices is therefore a challenge that concerns industry and policy makers alike. As engineers know, today’s embedded systems are often very complex, consisting of software and firmware, PCBs with digital and analog components and, of course, very complex ICs, which include CPUs that make a device “smart.”
