This thesis summarizes the research achievements of the project “High-Security and Low-Power Integrated Circuits and Systems for IoT Design, Analysis, and Implementation” funded by the Ministry of Science and Technology. The project is an integrated project proposed by the VLSI/CAD group in the Department of Electrical Engineering at National Cheng Kung University. The overall goal is to develop high-security and low-power IoT circuits and systems. To achieve this, the project team has developed two IoT systems for practical scenarios. The first system is the “High-Security and Low-Power Fish Farming Monitoring System,” which collects information such as water temperatures, fish images, and fish recognition results from the sensing end. The collected data is transmitted to the application end for user utilization using multiple secure and energy-efficient techniques. The second system is the “Lead-Free Piezoelectric Acceleration Sensing System for Monitoring Unmanned Aerial Vehicle Behavior.” This system can determine whether a drone is malfunctioning or poses a potential risk based on the acceleration of motor vibrations sensed by the accelerometers. It can promptly issue warnings according to the situation to ensure safe flight operations. For these two IoT systems, we have developed multiple technologies in various fields, including high-security and low-power circuit components and sensors, secure architectures of microprocessors and memory, low-power analog-to-digital converters, IoT network security protection systems, low-power radio frequency transmitters and receivers, as well as security designs and security testing architectures of the digital circuits. These technologies were designed to meet the security requirements and low-cost specifications of IoT applications.
