In IoT, there are a wide range of electronic devices (cameras, mobiles and sensors) that are interconnected. These devices gather and transmit huge volume of data every day by various means of devices. Because of these connected devices, there is a great risk of device and server manipulation, falsifies data and later impact on various application platforms. These devices collects data and uploads on server that store large data volume in databases, then application extract information by analyzing it based on which various services are provided. In this data flow, S/W in the upper layer rely on the H/W in the lower layer, which contains information collecting devices. If the collected data is altered, services in the upper layer could be interrupted. Therefore, to ensure service continuity in the IOT, it is important to secure the hardware layer. In this paper, we focus on hardware level security in IoT systems and various techniques such as HSM, TPM, FPGA, PUF, DICE, etc. for physical security of IOT systems.
