双向直接通信协议可以被认为是安全的吗?

Can Two-Way Direct Communication Protocols Be Considered Secure?

Mladen Pavicic

摘要:

我们考虑攻击的双向量子密钥分发协议中,一个不可检测的窃听者复制的消息模式中的所有消息。我们表明,在攻击下,没有干扰的消息模式,发送者和接收者之间的互信息总是恒定的,等于一。因此,最近的双向协议的安全性证明不能被认为是完整的,因为它们不包括所考虑的攻击。

英文摘要:

We consider attacks on two-way quantum key distribution protocols in which an undetectable eavesdropper copies all messages in the message mode. We show that under the attacks there is no disturbance in the message mode and that the mutual information between the sender and the receiver is always constant and equal to one. It follows that recent proofs of security for two-way protocols cannot be considered complete since they do not cover the considered attacks.
