The Detection and Performance Analysis of Covert Communication in Physical Layer

隐蔽通信是指在无线通信过程中,利用隐蔽技术使监测人无法检测到无线传输的存在,使得信息在传递过程中受攻击的风险大大降低。论文主要研究物理层隐蔽通信的检测方法和性能分析,首先,在现有隐蔽通信研究的基础上归纳出物理层隐蔽通信的理论框架;其次,阐述了看守者的检测度量方法及其检测性能分析;第三,以文献比较的方式对隐蔽通信的性能和仿真结果的评价进行了分析,最后,总结了一些撰写本文时未解决的技术挑战,并讨论了隐蔽通信的未来趋势。

Covert communication refers to the use of covert technology to make the monitor unable to detect the existence of wireless transmission in the process of wireless communication, which greatly reduces the risk of information being attacked in the process of transmission. This paper mainly studied the detection methods and performance analysis of physical-layer covert communication. Firstly, the theoretical framework of physical layer covert communication was summarized on the basis of existing research on covert communication. Secondly, the detection measurement method and detection performance analysis of the warden were described. Thirdly, the evaluation of the performance and simulation results of covert communication was analysed by means of literature comparison. Finally, some technical challenges which remain unresolved at the time of writing are summarized and the future trends in covert communication are discussed.
