互联网通信中信息隐藏技术的应用

The application of the hiding information technology in Internet communication

分析几种基于TCP和IP协议的信息隐藏方法的原理和优缺点,提出了一种基于TCP/IP协议的隐蔽信道模型。在源主机向目的主机发送秘密数据时,结合隐蔽信道模型,达到安全性和有效性相对较高的目的,并在此基础上设计并实现了一个基于TCP和IP协议字段的秘密数据传输模型。实验表明,该方案正确、有效,对实际工程中的信息隐藏有较高的参考价值。

In this paper,we analyzed the principles,the advantages and the disadvantages of hiding information technology and proposed a new method of hiding information based on TCP and IP protocol.We found it safer and more efficient to use the new method to send secrete data from the source host to the target ones.It is proved that such a secrete data transmission model designed on the base of TCP and IP protocol is practical and efficient in real information programs.
