热辐射无特征通信的复用方法

中文摘要 AI 辅助

利用半导体器件的中红外发射进行隐蔽通信仍是一个相对未被探索但前景广阔的机会。负发光现象为实现无特征隐蔽通信提供了一种方法，其中发射光电器件的净红外发射被平衡到与环境热背景相同。在这项工作中，我们实际演示了通过热辐射信道进行隐蔽数据传输，数据速率高达100 kbps。此外，我们展示了多种额外的复用技术，这些技术通过实现零瞬时光学发射，使所提出的热辐射通信方法更难被截获，同时如果利用足够空间或光谱分辨率的观测，仍可被检测到。最后，我们讨论了所提出方法可用于实现安全无特征通信的各种应用场景。

英文摘要

Using mid-infrared emission from semiconductor devices for covert communications remains a relatively unexplored and yet promising opportunity. The phenomenon of negative luminescence allows for a method of signatureless covert communications where the net infrared emission of an emitting optoelectronic device is balanced to be identical to the ambient thermal background. In this work we provide a practical demonstration of covert data transfer over a thermoradiative channel with data rates up to 100 kbps. In addition, we demonstrate several additional multiplexing techniques that make the proposed thermoradiative communications method more secure against interception by achieving zero instantaneous optical emission, while remaining detectable if a sufficiently spatially or spectrally discerning observation is utilised. Finally, we discuss various application scenarios in which the proposed methods can be used to achieve secure signatureless communications.
