Authentication and Data Protection Mechanism in IoT Devices

Abstract— Due to the rapid development of Internet of Things (IoT) technology, it is becoming more frequently used in everyday life and industrial applications. While these devices provide great convenience in our daily lives, they are also subject to serious security threats, including malware infections, DDoS attacks, data theft, identity theft, man-in-the-middle attacks, physical security threats, firmware vulnerabilities, lack of authentication and encryption, supply chain attacks, and user errors. These threats make the devices vulnerable to attacks leading to data leakage and service disruption.

The aim of this paper is to analyze the authentication and data protection mechanisms in IoT devices and to explore the current challenges and feasible solutions. It is shown that improved authentication mechanisms can significantly increase the security of devices and thus better protect user privacy. Finally, the paper also presents suggestions and directions for future research.
