中文摘要：

针对图像隐密算法中加密秘密信息的问题,将Kerckhoffs原则应用到图像隐密算法中.在对比密码技术和隐密技术的异同点的基础上,分析了在图像隐密算法中使用Kerckhoffs原则的重要性,通过使用掩护图像集,将秘密信息分散隐藏在掩护图像集合的某个子集中,从而减少含密图像被攻击者发现的几率,并且在算法中使用加密手段抵抗密码分析者的攻击.分析表明,本文提出的基于Kerckhoffs原则的图像隐密算法可以提高隐密的安全性,保证秘密信息不被攻击者获得.

英文摘要：

Aiming at the encryption of the secret information in image steganography scheme,the article applies Kerckhoffs＇ principle in image steganography.Based on the comparison between encryption and steganography,the article analyzes the importance of Kerckhoffs＇ principle.In order to reduce the exposure probability of the stego,the secret information is hidden in a set of cover-images.The scheme uses encryption arithmetic to resist the attackers＇ cryptanalysis.Analyses show that the image steganography scheme introduced in this article can improve the security of the image steganography scheme and keep the information secret.
