提出了一种对量子加密系统的新型攻击。在这次攻击中，夏娃利用了鲍勃方案中的各种光学缺陷，并构建了光脉冲，因此鲍勃没有将他的检测结果与正常人区分开，而它们为鲍勃提供了在夏娃酌情下选择的基础和位价值。考虑将此攻击应用于鲍勃一侧具有被动基础选择的系统。同样，讨论了使用此或特洛伊木马攻击分解成量子加密链接的一般工作流程。
A new type of attack on quantum cryptography systems is proposed. In this attack, Eve utilizes various optical imperfections in Bob's scheme and constructs light pulses so that Bob does not distinguish his detection results from normal, whereas they give Bob the basis and bit value chosen at Eve's discretion. Applying this attack to systems with passive basis choice on Bob's side is considered. Also, a general workflow of breaking into a running quantum cryptolink using this or Trojan horse attack is discussed.
