摘要

几年前，Hong 等人（Quantum Inf Process 16:236, 2017）提出了一个使用单光子的量子身份验证协议，并可在目前可用的量子硬件上执行。Zawadzki 后来发表了两篇针对该协议的攻击文章，并在同一作品中提出了缓解方法。在这篇评论中，我们指出了一个额外的漏洞，它导致验证者爱丽丝在每次身份验证尝试中都会泄露一定比例的秘钥。后者是由于诱饵状态的生成和管理策略存在问题。最后，我们展示了一种简单的缓解方法来解决这个问题。

Comment on “quantum identity authentication with single photon”

A few years ago Hong et al. (Quantum Inf Process 16:236, 2017) proposed a quantum identity authentication protocol using single photons and executable on currently available quantum hardware. Zawadzki later published two attacks on this protocol, and suggested a mitigation in the same work. In this comment we point out an additional vulnerability that causes the prover Alice to leak a percentage of her secret key at every authentication attempt. The latter is due to a problematic policy in the generation and management of decoy states. We conclude by showing a simple mitigation that addresses the issue.
