The well-known RF penetration method is implemented on the quantum cryptosystems. In this study, RF radiations from the single photon detectors in a quantum key distribution system are intercepted. It was found that the data contents of a quantum transmission system can be detected from the vicinity of the receiving parties by exploiting the radiations of avalanche effect of single photon detectors. We showed that any Geiger-mode avalanche photodetector acts like a downconverter that converts the optical-wavelength photons to radio-wavelength photons. In our experiment, the fingerprints of the avalanche radiations from commercial single photon detectors were fed to a trained deep learning neural network, and the bit content of quantum transmission was cloned with >99% accuracy up to a distance of 2 meters from the detectors. We also speculate on the enhancement of the key cloning accuracy and range of the eavesdropping.

通过光子探测器的射频指纹攻击量子密码系统



众所周知的射频穿透方法是在量子密码系统上实现的。在这项研究中,量子密钥分配系统中的单光子探测器发出的射频辐射被拦截。人们发现,通过利用单光子探测器的雪崩效应辐射,可以从接收方附近检测到量子传输系统的数据内容。我们表明,任何盖革模式雪崩光电探测器都像下变频器一样,将光学波长光子转换为无线电波长光子。在我们的实验中,来自商用单光子探测器的雪崩辐射指纹被输入经过训练的深度学习神经网络,并且在距探测器 2 米的距离内以 >99% 的精度克隆量子传输的比特内容。我们还推测密钥克隆精度和窃听范围的增强。
