RSA Implementation Using FPGA

In this work, the cryptographic technique known as RSA is designed and implemented, with the goal of becoming a standard in secure communication systems. The basic idea of this algorithm is to create a confidential communication channel in between two parties (sender, and receiver). Verilog is used to code each module or block, and the Xilinx ISE₁4. 7 Design Suite is used to synthesize and simulate the code. A trade-off between speed, power, and space is offered, and the design is geared toward speed. FPGA is used as hardware to increase the speed and make the algorithm more secure. Our goal is to demonstrate, as a significant practical outcome, that the RSA algorithm can be implemented at secure bit lengths on a single piece of commercial hardware—FPGA and the study covers the design, optimization, and challenges of implementing RSA modules on FPGA, emphasizing modular exponentiation, key generation, and data handling.
