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.
