论文摘要
实施高速量子密钥分布〜（QKD）已成为该领域的主要重点之一，该领域会为应用程序产生高密钥生成率。为了实现高速QKD，开发和使用量身定制的技术来快速生成和检测量子状态。但是，这些技术可能会引入独特的漏洞，以损害QKD系统的安全性。在本文中，我们研究了自差异〜（SD）雪崩光电二极管〜（APD）检测器的漏洞，通常用于QKD系统中的高速检测，并在强脉冲照明攻击下证明了SD APD检测器的实验测试。这次攻击呈现出盲目的稳定性，并有助于窃听者在不引入额外QBER的情况下学习秘密钥匙。基于此测试，我们提出了一组保护SD APD检测器免受强脉冲照明攻击的标准。
Implementation of high-speed quantum key distribution~(QKD) has become one of the major focus in the field, which produces high key-generation rate for applications. To achieve high-speed QKD, tailored techniques are developed and employed to quickly generate and detect quantum states. However, these techniques may introduce unique loopholes to compromise the security of QKD systems. In this paper, we investigate the loopholes of self-differencing~(SD) avalanche photodiode~(APD) detector, typically used for high-speed detection in a QKD system, and demonstrate experimental testing of SD APD detector under strong pulse illumination attack. This attack presents blinding stability and helps an eavesdropper to learn the secret key without introducing extra QBER. Based on this testing, we propose a set of criteria for protecting SD APD detectors from the strong pulse illumination attack.
