对“基于量子加密的量子密钥分发”一文的评论

Comment on "Quantum key distribution via quantum encryption"

Fei Gao, Sujuan Qin, Qiaoyan Wen, Fuchen Zhu

摘要:

在论文[Zhang,Li and Guo,Phys.Rev.A64,024302(2001)]中,提出了一种基于量子加密的量子密钥分发协议,在该协议中,量子密钥可以重用。然而,它表明,如果Eve采用一种特殊的策略来攻击,该协议变得不安全,因为重用的量子密钥。也就是说,夏娃可以在不被发现的情况下引出关于密钥位的部分信息。最后,对Zhang-Li-Guo协议提出了一种可能的改进。

英文摘要:

In the paper [Zhang, Li and Guo, Phys. Rev. A 64, 024302 (2001)], a quantum key distribution protocol based on quantum encryption was proposed, in which the quantum key can be reused. However, it is shown that, if Eve employs a special strategy to attack, this protocol becomes insecure because of the reused quantum key. That is, Eve can elicit partial information about the key bits without being detected. Finally, a possible improvement of the Zhang-Li-Guo protocol is proposed.
