| 摘 要： | 目前诱骗态量子密钥分发系统被许多实验系统所采用,并且一些文献声称诱骗态具有理想的安全特性。诱骗态在抵抗量子数分离攻击方面有一定的优势,但是,它并不能完全解决量子密钥分发系统的安全问题,并且目前被广泛采用的改进的诱骗态方案在窃听检测环节存在明显的缺陷,不可能是一个具有理想安全特性的解决方案。文中对诱骗态量子密钥分发系统的安全性漏洞与缺陷进行了分析和评论。

| Abstract: | Decoy-state quantum key distribution system is adopted by many experiment systems,and is declared to be of ideal security by some paper.In fact,decoy-state system has some advantages in efficiency and communication length,but some flaws exist in its eavesdropping detection procedure,so it is not an ideal solution with perfect security.This paper mainly presents a special photon number splitting attack on decoy state system and discusses the security loophole of this system. |
