摘要
文章首先介绍隐蔽信道的基本概念以及网络隐蔽信道的研究现状,然后着重总结几种典型的网络时间隐蔽信道,最后综述网络时间隐蔽信道领域中经典的防御技术和方法。文章试图为该研究方向勾勒出一个较为全面的概貌,为该领域的研究人员提供有益的参考。
This paper firstly introduces the concept of covert channel, and then gives an overview of network- based covert channels. Next, it summarizes several typical network-based covert timing channels. Finally, it surveys the classic countermeasures in the field of network-based covert timing channels. This paper attempts to give a comprehensive outline for this research direction, and provides a useful reference for the researchers.
