FPGA-based Low-Power Encryption using the Elliptic Curve Digital Signature Algorithm

The proposed work gives a solution to the increasing demand for resource-constrained environments for low-power cryptographic solutions: field-programmable gate array (FPGA) implementation of the Elliptic Curve Digital Signature Algorithm (ECDSA) for low-power encryption. By leveraging the parallel processing capabilities of FPGA, the suggested approach effectively mitigates power consumption while maintaining security. The study extensively analyzes the hardware’s architecture, design elements, and energy-conserving strategies explicitly developed for FPGA implementation. The results indicate that the ECDSA-FPGA system exhibits superior processing speed and energy efficiency compared to conventional encryption methods. This contribution elucidates the imperative nature of striking a harmonious equilibrium between energy efficiency and security in contemporary cryptographic systems, thereby bolstering the progress towards secure communication in the Internet of Things and wearable technologies.
