摘要
量子安全直接通信是量子密码学的一个重要分支。最近,一种基于中间基的量子安全直接通信方案被提出(Liang et al. in Front Phys 18(5):51301, 2023 https://doi.org/10.1007/s11467-023-1284-4)。该方案通过利用中间基,提高了安全检测和信息编码的效率。然而,本文指出了上述方案存在的两个严重问题。首先,由于中间基只是贝尔基的一个变体,因此它未能利用两个不同的基。因此,基于中间基的量子安全直接通信方案无法实现所承诺的高效率。其次,即使用其他量子基础替代中间基础,修正后的量子安全直接通信方案也无法实现承诺的高效率,因为接收器无法从最终纠缠对中正确解码密文。设计正确高效的量子安全直接通信协议至关重要。这项工作可以提醒量子安全直接通信的开发者在提高方案的稳健性和效率时避免此类陷阱。
Problems of a quantum secure direct communication scheme based on intermediate-basis
Quantum secure direct communication is a significant branch of quantum cryptography. Recently, a quantum secure direct communication scheme based on intermediate-basis was proposed (Liang et al. in Front Phys 18(5):51301, 2023 https://doi.org/10.1007/s11467-023-1284-4). It is believed that the scheme can improve the efficiencies of security detection and information encoding by utilizing the intermediate-basis. However, this paper points out two serious problems with the aforementioned scheme. Firstly, it fails to utilize two distinct bases since the intermediate-basis is merely a variant of the Bell basis. Accordingly, the quantum secure direct communication scheme based on intermediate-basis cannot achieve the promised high efficiency. Secondly, even if the intermediate-basis is substituted with another quantum basis, the modified quantum secure direct communication scheme cannot achieve the promised high efficiency because the receiver cannot correctly decode the secret message from the final entangled pairs. It is crucial to design correct and efficient quantum secure direct communication protocols. This work can remind the developers of quantum secure direct communication to avoid such pitfalls when they enhance the robustness and efficacy of their schemes.
