Abstract
The new technology solutions are playing an important role in the hardware security. One of the latest techniques is the use of the Memristor as an encryption element. In this paper, it has been introduced a two-column array inductor for Memristor-Based Wireless Power Transfer (M-WPT) systems. The traditional WPT circuits are based on switches, which do require a control circuit for timing and have low data encryption factor. By adopting the memristive Chua`s circuit with the chaotic behaviour characteristic, it is possible to create a symmetrical dual-key cryptography. Furthermore, in this innovative solution, the high inductance value of the traditional Chua circuit can be further reduced by using the dynamic effects of the coils flux linkage. The simulation results exhibit the dual-scroll attractors phase portrait, which is available for encryption features. Therefore, the data collected from the phase portrait are used as true random number generator in Python code. Instead of using algorithms, the code can create a symmetrical key for an unique chaotic cryptography. In order to build a prototype, it has been created a PCB design for the whole system. The experiment highlights the unpredictable voltage and current and validates the chaotic behaviour of the transmitter and receiver.
Highlights
The concept of the Internet of Things is based on the ability of physical objects with embedded technology to communicate with each other or with other systems, transmit data and work in a synchronised way
Near Field Communication (NFC) [3] is a low energy wireless transfer technology operating at 13.56 MHz frequency, with few centimetres of access distance used in IoT devices
In this article,in order to improve the security in IoT devices, we introduce the memristor
Summary
The concept of the Internet of Things is based on the ability of physical objects with embedded technology to communicate with each other or with other systems, transmit data and work in a synchronised way. The HCE [7], [8] is the software architecture that provides accurate virtual representation of different electronic identification cards (access, transit and banking) This technology makes it easier for retailers to deliver payment card through mobile closed-loop contact-less payment solutions, as well as provides real-time payment card delivery, and enables a simple implementation scenario that does not require changes to the software within payment terminals. We propose an array memristorbased architecture for WPT systems This is a new research study adopting the memristor in wireless power transfer, there are no other references for this system.
