邮件文本的信息隐藏技术研究

The research and designing of the hidden technology based on text message of E-Mail Major:Information security

随着信息化的发展,保密通信变得越来越重要。当今,电子邮件是人与人通信的重要工具之一,因此应用它进行信息隐藏已成为保密通信的重要研究课题.本文提出一种模式变换的电子邮件信息隐藏算法.这种算法是利用隐藏信息构造信息隐藏矩阵,利用文字模式构造模式系数矩阵,再用这两个矩阵构造隐藏矩阵,最后用隐藏矩阵对电子邮件的文字模式进行模式变换.本文还根据信息熵理论,分析了这种算法的信息隐藏容量.我们采用所提出的算法,设计了计算机程序,进行了信息隐藏实验.实验表明,我们的算法具有很好的信息隐藏效果.

Secure communication become more and more important with the advent of the information age.E-mail has become one of the most important tools for communication in public life today.Consequently, Information hiding technology based on E-mail plays a significant part in the field of secure communication.We present a method using pattern transformation to hide information in E-mail text. First,we build an information hiding matrix by the secret information and construct a pattern coefficient matrix by text pattern.Second,we use these two matrixes to build a hiding matrix which is in action of the text pattern transformation.In addition,we analyze the capability volume of our method by the theory of entropy.At last,we design a program based on our method.Extenneively tested,this method makes the information hiding effectively and efficiently.
