| 摘 要： | 分析总结了基于JTC的光学加密系统密钥设计问题,提出了采用模糊控制迭代算法来代替G-S算法生成密钥,并与利用G-S算法和平滑修正法所得密钥进行了对比。理论计算和计算机模拟实验结果显示,模糊控制迭代算法的迭代结果其振幅均方误差为0.69%,振幅不均匀度为1.01%。采用模糊控制迭代算法生成的密钥解密质量优于G-S算法和平滑修正法。

| Abstract: | After analyzing and summarizing the problem of key design in JTC encryption system,an Iterative Algorithm based on Fuzzy Control Theory(IAFC) in place of G-S was proposed,and the comparison with G-S and Sleek Revise(SR) algorithms was given.Computer simulation experiment,as well as theoretical research show that the amplitude mean square error of the iterative output derived from IAFC is 0.69%,and the amplitude un-uniformity is 1.01%.Therefore the decryption quality of key design from IAFC is better than that of key designed from G-S and SR algorithms. |
