在这项工作中，我们提出了一种自由空间光通信系统，它将混沌通信与量子密钥分配(QKD)相结合，与现有的自由空间光通信技术(如ASN-狭缝干涉仪)相比，可以获得更大的安全性和范围。我们利用Lorenz混沌发送器和接收器模型，这两个模型是固有的自同步，以产生混沌信号作为数据载体。使用Lorenz混沌通信系统在经典信道上安全地传输数据，而使用量子信道通过QKD和公钥密码协议的组合来安全地交换关键的同步参数。由于FSO通信已经被包括NASA和ESA在内的空间机构使用，我们提供了一种将混沌通信和量子密钥分配相结合的空间任务的操作概念，以实现端到端的加密深空光通信链路。我们的实验工作包括高分辨率单光谱和多光谱图像的实时传输，在一定噪声水平下的误码率测量，以及通过混沌系统的动态重构来评估传输的安全性和鲁棒性。
In this work, we propose a free-space optical (FSO) communication system that combines chaotic communications with quantum key distribution (QKD) to achieve greater security and range compared to existing FSO techniques such asN-slit interferometers. We utilize Lorenz chaotic transmitter and receiver models, which are inherently auto-synchronizable, to generate chaotic signals used as data carriers. Data are transmitted securely over a classical channel using the Lorenz chaotic communication system, while a quantum channel is used for securely exchanging critical synchronization parameters via a combination of QKD and public-key cryptography protocols. Because FSO communications have been utilized by spaces agencies including NASA and ESA, we provide a concept of operations for a space mission combining chaotic communications and QKD to achieve an end-to-end encrypted deep-space optical communications link. Our experimental work includes successful real-time transmission of high-resolution single-spectral and multi-spectral images, measurement of bit-error-rate over a range of noise levels, and an evaluation of security and robustness of transmissions with dynamic reconfiguration of the chaotic systems.
