摘要： 文章提出的加密方法是在DES加密基础上,构造充满噪声的图像,再将一级密文嵌入到应用来冗余机制的噪声图中,完成二级加密,生成网络传输的二级密文的加密方法。证明了该方法是具有高保密性能而且方便易行的一种新型加密思想方法,具有很好的发展和应用前景。

Abstract: Firstly,the paper encrypts the plaintext into once-ciphertext with DES algorithm.Secondly,it makes redundant-space by using image full of noise.Finally,it encrypts the once-ciphertext with the noisy image into twice-ciphertext which is transfered by the network.It proves that making redundant-space method is an advanced encryption method with high performance of stronger security and higher convenience.It has a bright future.
