Hardware Aware Polyalphabetic Cipher Design Using Spin-Orbit Torque Controlled Spintronic Devices

This brief presents a hardware-aware polyalphabetic cipher leveraging spin-orbit torque (SOT)-based spintronic devices. Utilizing the randomness and non-linear magnetization dynamics of spintronics, the design introduces hardware-driven entropy for enhanced encryption. Dynamic shift values and a hardware-based substitution box (S-box) achieve moderate non-linearity and uniform functionality. Experimental results validate the system’s robustness across temperature and device-to-device variations, demonstrating the potential of spintronics for lightweight, secure cryptographic applications.
