Hardware Root Of Trust for IoT Security In Smart Home Systems

Authentication is a key challenge in Internet of Things (IoT), and it is a foundation for data integrity and confidentiality. Security and privacy preservation are crucial for the integration of IoT in our daily life. Due to the resource-constrained nature of IoT sensors, it is not applicable to utilize traditional cryptography techniques in IoT domains. Wireless network devices are used for IoT in a wide range of applications. In this paper, we propose an efficient and secure authentication architecture for IoT. Compared to the existing constrained applications Protocols, the proposed architecture increases efficiency by minimizing the number of message exchanges and implementing lightweight cryptosystem. Also, the proposed architecture increases security by eliminating any key storage on device memory as well as third party certificate authority. The main idea of the proposed architecture is to integrate lightweight cryptography and hardware security approaches to be the basis to face the current security challenges.
