摘要： 通过对IP包的数据结构和传输过程的分析，指出在通信过程中，有选择地修改IP包的源IP地址和目的IP地址并不会影响IP包在通信双方之间的传输。提出把秘密消息映射到IP地址，并替换IP包相应的IP地址的信息隐藏方法。验证了方法的可行性，对其性能进行了分析，指出利用该方式来进行信息隐藏具有较高的安全性。

Abstract: This paper analyzes the structure and transmission of IP packets in network communication, and points out that it doesn’t influence the routing by modifying partially the IP addresses. Based on this feature, it presents a new steganography scheme that maps the secret messages into IP addresses and replaces those of IP packets. It proves the feasibility, and the analysis of performance shows the security of the scheme.

Key words: information security, steganography, channel, network protocol, IP address
