基于卡登格子的信息隐藏方法

A Cardan Grille Information Hiding Method Based on Image'Labels

传统的卡登格子虽然能生成载体,但是需要人工构造有意义的栽体,费时费力。将密码学中简单的单表代替与信息隐藏相结合,提出了一种满足柯克霍夫准则的现代卡登格子的信息隐藏方法。该方法基于生成模型,从消息驱动直接生成含密载体,利用双方共享的卡登格子信息进行消息的隐藏和提取。利用生成对抗网络给定任意的标签组合都能生成有意义的图像这一特性,实现了传统卡登格子信息隐藏的自动化操作。从实验上验证了该方法的合理性和有效性,并分析了该方法的安全性。

Although the traditional Carden grille can generate carriers,it requires manual construction of a meaningful carrier,which takes time and effort.We combine the simple single table substitution of cryptography with information hiding to propose a new information hiding method of modern Cardin grille that satisfies the Kirchhoff criterion.This method is based on a generative model,generates dense carriers directly from message drivers, and uses Cardin grille information shared by both parties to hide and extract messages.We can generate a meaningful image by using the combination of any given label into the GANs, which realizes the automatic version of the traditional Carden grille information hiding.The rationality and effectiveness of the method are verified experimentally,and the security of the method is analyzed.
