| Abstract: | An optimal modular multiplication algorithm of optimal normal bases in elliptic curve cryptography is provided in this paper.It also proposes an FPGA design schedule and finite state machine model aiming at this algorithm.In this paper the finite state machine model is implemented in Verilog HDL based on Xilinx FPGA device,and HDL simulation and synthesis is finished in ISE and ModelSim development tools.Experiments show that the modular multiplication design schedule in this paper can work at a high speed and run in EC-Elgamal system well. |
