High-Security Hardware Module with PUF and Hybrid Cryptography for Data Security

Abstract: This research highlights the rapid development of technology in the industry, particularly Industry 4.0, supported by fundamental technologies such as the Internet of Things (IoT), cloud computing, big data, and data analysis. Despite providing efficiency, these developments also bring negative impacts, such as increased cyber-attacks, especially in manufacturing. One standard attack in the industry is the man-in-the-middle (MITM) attack, which can have severe consequences for the physical data transfer, particularly on the integrity of sensor and actuator data in industrial machines. This research proposes a solution by developing a hardware security module (HSM) using a field-programmable gate array (FPGA) with physical unclonable function (PUF) authentication and a hybrid encryption data security system. Experimental results show that this research improves some criteria in industrial cybersecurity, ensuring critical data security from cyber-attacks in industrial machines.
