摘要

单光子光探测与测距（LiDAR）传感器一直面临着严重的光干扰和光攻击问题。对发射激光进行随机调制可以有效地抑制干扰和反击。基于激光雷达单光子探测的量子随机数发生器（QRNG）已成为生成真随机数的重要解决方案。传统的基于光子事件计数值奇偶性的QRNG （CntOE-QRNG）在低光子事件率下性能较差。本文提出了一种基于光子事件间隔宇称判别的QRNG方法（IntOE-QRNG）。实验证明，在低光子事件率条件下，ingo - qrng具有更大的优势。在分析这两种方法优缺点的基础上，本文最后提出了一种结合这两种方法的优化QRNG，以适应不同的光子事件速率条件。

Optimized Quantum Random Number Generator for Single Photon LiDAR Interference Suppression

Single photon light detection and ranging (LiDAR) sensors have been facing serious issues of light interference and optical attacks. Random modulation of transmitted laser can effectively suppress interference and counter attacks. Quantum Random Number Generator (QRNG) based on single photon detection of LiDAR has become an important solution for generating true random numbers. The performance of traditional QRNG based on the parity of counting values of photon events (CntOE-QRNG) is poor under low photon event rate. This letter proposes a novel QRNG method based on parity discrimination of photon event interval (IntOE-QRNG). It is proved that the IntOE-QRNG has more advantages under the condition of low photon event rate. Based on the analysis of the advantages and disadvantages of these two methods, this letter finally proposes an optimized QRNG that combines these two methods to adapt to different photon event rate conditions.
