摘要
本文研究了文本冗余变换以及伪装传输。其技术路线是首先通过一个文本生成器产生一段有意义的参考文本来掩饰将要传输的机密文本,然后将不具有冗余度的文本文件通过冗余变换使之具有冗余度,再对具有冗余度的参考文本和机密文本进行一次性码本的编码,最后两者异或运算形成隐藏密码嵌入图像或声音中,实现机密文本的伪装传输。
We research redundancy transform of text and steganography transmissionhere. The route of technology is: first, to hide the transmission of secret text throughreference text produced to same size of secret text by a text creater, then it transformswithout redundant digit into with redundant digit by redundancy handling of the text, one-time pads is coded on the redundant secret text and reference text, and last, two code isform to hide-cryptogram by exclusive OR operation, and then inlay it into image and soundto realize the transmission of secret text steganography.
