论文摘要
随机性主要是随机数的形式，是许多加密任务安全的基本先决条件。即使对手完全了解协议，甚至可以控制随机性源，也可以提取量子随机性。但是，对手可以通过量身定制的检测器盲攻击进一步操纵随机性，这是由具有可信赖探测器的协议所遭受的黑客攻击。在这里，通过将无单击事件视为有效事件，我们提出了一个量子随机数生成协议，该协议可以同时解决源漏洞和凶猛的量身定制的检测器盲目攻击。该方法可以扩展到高维随机数生成。我们通过实验证明，我们的方案能够以每脉冲0.1位的生成速度生成二维测量的随机数。
Randomness, mainly in the form of random numbers, is the fundamental prerequisite for the security of many cryptographic tasks. Quantum randomness can be extracted even if adversaries are fully aware of the protocol and even control the randomness source. However, an adversary can further manipulate the randomness via tailored detector blinding attacks, which are hacking attacks suffered by protocols with trusted detectors. Here, by treating no-click events as valid events, we propose a quantum random number generation protocol that can simultaneously address source vulnerability and ferocious tailored detector blinding attacks. The method can be extended to high-dimensional random number generation. We experimentally demonstrate the ability of our protocol to generate random numbers for two-dimensional measurement with a generation speed of 0.1 bit per pulse.
