In this paper, a kind of chaos encryption system is presented based on chaotic encryption algorithm and traditional encryption algorithm, and hardware is implemented by using the FPGA technology. According to discrete and digital technologies, Henon Map and Logistic Map are applied, and chaotic iteration sequence is generated by using Verilog HDL language and FPGA technology. By combining the traditional iteration algorithm, the files are encrypted and decrypted. Based on Xilinx FPGA exploitation platform, secret communication experiments on Internet are successefully. The devise has potential prospective applications in internet secrecy communication.
