论文摘要
在过去的几年中，提出了探测器盲目攻击，它们可能威胁到QKD系统的安全性。即使尚未将完整的QKD系统入侵，但重要的是要考虑对策以避免信息泄漏。在本文中，我们根据使用多像素探测器的使用提出了针对此类攻击的新对策。我们表明，使用这种方法，我们能够估算出窃听器在钥匙交换的信息上的上限。最后，我们基于SNSPD来测试一个多像素检测器，以表明它可以满足我们的对策有效的所有要求。
Detector blinding attacks have been proposed in the last few years, and they could potentially threaten the security of QKD systems. Even though no complete QKD system has been hacked yet, it is nevertheless important to consider countermeasures to avoid information leakage. In this paper, we present a new countermeasure against these kind of attacks based on the use of multi-pixel detectors. We show that with this method, we are able to estimate an upper bound on the information an eavesdropper could have on the key exchanged. Finally, we test a multi-pixel detector based on SNSPDs to show it can fulfill all the requirement for our countermeasure to be effective.
