摘要
无线隐蔽通信是将消息隐藏在无线通信数据帧和信号中进行隐蔽传输的技术,属于无线通信和信息隐藏技术的交叉领域,其理论与技术的研究方兴未艾.本文分析了无线隐蔽通信的系统模型和主要能力要素,总结归纳了噪声式隐蔽信道容量的理论以及链路层、编码层、调制层和信号层中无线隐蔽通信技术的研究进展,并指出了需要进一步研究的问题.
Wireless covert communication is the technology of hiding messages in wireless communication data frames and signals for covert transmission,which belongs to the cross-field of wireless communication and information hiding technology.This paper analyzes the system model and main ability factors of wireless covert communication,summarizes the theory of noise-type covert channel capacity and the research progress of wireless covert communication technology in link layer,coding layer,modulation layer and signal layer,and gives the problems that need further study.
