We developed a modified version of a conventional (BB84) quantum key distribution protocol that can be understood and implemented by students at a pre-university level. We intentionally introduce a subtle but critical simplification to the original protocol, allowing the experiment to be assembled at the skill level appropriate for the students, at the cost of creating a security loophole. The security vulnerability is then exploited by student hackers, allowing the participants to think deeper about the underlying physics that makes the protocol secure in its original form.

面向大学预科生的动手量子密码学研讨会

我们开发了传统 (BB84) 量子密钥分发协议的修改版本，大学预科阶段的学生可以理解和实施该协议。我们有意对原始协议进行了微妙但关键的简化，允许以适合学生的技能水平组装实验，但代价是造成安全漏洞。然后学生黑客利用安全漏洞，让参与者更深入地思考使协议以其原始形式安全的底层物理原理。
