摘要
文中首先阐述了基于TCP/IP协议的信息隐藏原理,并利用ICMP协议信息隐藏的实现方法与修改TCP连接中IP首部的源地址的方法相似性,提出一种利用ICMP进行数据隐藏的方法。即源主机向目的主机发送隐藏数据时可以对IP协议头和TCP协议头双重修改,并利用ICMP的IP欺骗隐藏自身的IP地址,以达到信息容量最大和安全性相对较高的效果。实验结果实现了信息隐藏,验证了该方法的正确性,对实际工程中的数据隐藏有一定的参考价值。
The principle of information hiding based on TCP/IP protocol is described first. And then a new information hiding method by using ICMP protocol is proposed. The information hiding method by using ICMP protocol is similar to modifying the source address of IP package head in TCP connection. When source host transmits secret data to goal host, both IP package head and TCP package could be modified simultaneously and IP address itself be hidden by using IP spoofing in ICMP protocol. The scheme could achieve the biggest information capacity and relatively high security. The experiment indicates that this method id practicable and of some reference value.
