Design of Signcryption system using PHOTON Hash Function on FPGA platform

The rapid expansion of the Internet of Things (IoT), and embedded systems has raised the demand for lightweight and efficient cryptographic technologies that can provide reliable communication while using minimal hardware resources. This article describes an FPGA-based signcryption system that uses the lightweight PHOTON hash function to accomplish confidentiality, integrity, and authentication. The suggested architecture is made up of modules for key generation, encryption, and decryption that have been optimized for hardware deployment. The design was built on an Artix-7 FPGA and validated via functional simulation. Experimental findings show that message recovery and authentication are successful at a maximum operating frequency of 350.128 MHz, a throughput of 282.36 Mbps, and a total power usage of 149 milliwatts. The collected results demonstrate that the suggested architecture is suitable for resource-constrained secure interaction scenarios.
