Cyber threats are currently targeting not only the individual computers, but the industrial infrastructures managed by industrial control systems, that are often interconnected in large networks. The recent developments in the field of electronic devices, namely sensors and wearable equipment, and the evolution of communication technologies permitted the adaptation of Internet of Things (IoT) devices on a large scale. These IoT devices contains computing power, good connectivity, but are prone to a large number of cybersecurity vulnerabilities and attacks. This chapter is focused on describing some innovative hardware-based cybersecurity solutions de-signed especially for Internet of Things devices. The proposed solutions are based on physical unclonable functions (PUF) encryption methods. The first method is based on unique features which are the results of variable entries in the process of manufacturing semiconductor devices. An example of an encryption system already developed and available on the market is presented. The second method is based on the proper-ties of memristors, mainly the nonlinearity of the I–V characteristics and the particularities in their production process, which allow generating unique material states. By using this method, it is possible to generate very large random encryption keys, using few electrical components. This solution could be incorporated in various security systems that uses parallel communication channels to send and receive the voltage level to be used in reading the memristors, as well as to physically control the connection to the main data transfer channel, being it Ethernet, Wi-Fi or another broad-band connection.
