摘　　要：基于激光的漫反射能提供一种新型的快速便捷的陆上通信手段。针对强对抗环境中可能存在的窃听风险,基于物理层安全的原理建立了存在一个光源、一个合法接收者和一个窃听者的漫反射光通信系统模型。然后,对散射和漫反射两种不同接收方式的红外波段窃听链路损耗进行了理论分析和仿真比较。结果表明,在通常情况下,漫反射窃听的链路损耗更小、风险更大,应优先使用前向漫反射通信。A new fast and convenient means of terrestrial communication can be provided based on laser diffusion.For a strong antagonistic environment with the risk of being eavesdropped,a model of laser diffusion communication system with a light source,a legitimate receiver and an eavesdropper is established according to the principle of physical layer security.Then,the theoretical analysis and simulation comparison of infrared band eavesdropping link loss are performed for two different receiving modes of scattering and diffusion.The results indicate that,in general,diffusion eavesdropping has less link loss and a bigger risk,
