隐蔽通信技术是信息隐藏技术在通信保密领域的重要应用，是近年来信息安全领域研究的热点之一。文章提出一种基于网络行为特征的隐蔽通信模型，首先通过主机的网络行为特征判定两者之间通信最频繁通信特征，而后将秘密信息嵌入到多媒体载体中，最后将携带秘密信息的多媒体根据通信特征发送到接收方完成隐蔽通信。实验结果表明，该模型不仅能够将隐蔽通信行为掩盖于主机间正常的通信行为中，而且还可以提供较高的通信安全性。

As an important application in the field of information hiding technology in the field of communication security. Cov-ert communication technology is one of the hot research topic in information security field in recent years. Article puts forward a model of covert communication based on network behavior characteristics. Firstly, through the network behavior characteris-tics determine the host communication between the most frequent communication features. Then, embedding secret information into multimedia carrier. Finally, according to the characters of communication, sends multimedia which carries confidential in-formation to the receiving party and completes covert communication. The experimental results show that the model not only can hide in stealth communication behavior between hosts to normal communication behavior, and provide to high to the security of communication.
