论文摘要
我们提出了一个基于纠缠的量子位字符串承诺协议，其合成性在随机Oracle模型中得到了证明。该协议具有保留订婚消息隐私的附加属性。即使此属性对中间人的攻击没有弹性，但可以通过考虑各方通过身份验证的渠道进行通信来规避这种威胁。如果我们将随机的牙齿视为所谓的不封次函数，则该协议仍然是安全的（但不是私有的），在所谓的不良PUF模型中，在开放阶段之前的访问权限。
We propose an entanglement-based quantum bit string commitment protocol whose composability is proven in the random oracle model. This protocol has the additional property of preserving the privacy of the committed message. Even though this property is not resilient against man-in-the-middle attacks, this threat can be circumvented by considering that the parties communicate through an authenticated channel. The protocol remains secure (but not private) if we realize the random oracles as physical unclonable functions in the so-called bad PUF model with access before the opening phase.
