A Study on the Hardware-Based Security Solutions for Smart Devices

For enhanced secure services on smart devices, hardware-based security solutions are required. To this end, the hardware security module is required and it should be physically separated from a smart device. In this paper, we describe the considerations for applying a hardware security module on smart devices. In particular, as smart devices have a limited resource and use a battery, a hardware security module for smart devices should be considered above mobile environment. In this paper, we implemented the hardware security chip for smart devices. In addition, in order to test and equip the implemented chip to a smart device, we implemented the smartphone and verified the secure service on the smart device based on the chip.
