To get an image encryption algorithm with the features of high complexity,good safety and low cost of computing,a kind of image encryption algorithm based on chaos system with Markov portion was improved,it was made accord better with the idea of FPGA design without affecting the complexity and security of the algorithm,and it was realized on the development board XC5VLX110 Tusing Verilog HDL.Then,the encryption and simulation results indicate that the cipher image is safe enough because the characteristic of the original image was broken,which made it undistinguishable.And after decrypting the encrypted image,the original image was got,which verified the correctness of the system.Additionally,due to the hardware parallelism of FPGA,the efficiency of algorithm is much higher than that of those designed on other platforms.
