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.

• 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。
