Semi‐quantum key distribution is a very interesting new branch of quantum key distribution. It can be implemented when one or more participants are restricted to operate quantum states only on the quantum computational basis. Very recently, a mediated semi‐quantum key distribution protocol without invoking two participants' quantum measurement has been proposed. The protocol allows two “classical” participants without sophisticated quantum capability to establish a shared secret key under an untrusted third party. It is claimed that the protocol is secure against several well‐known attacks. However, in this paper, it is first pointed out that there exist three attacks “Measurement Attack, Modification Attack, and Collective Attack” on the mediated semi‐quantum key distribution protocol without invoking quantum measurement. By proposed attacks, a malicious third party can obtain the secret key without being noticed by legitimated participants.

在不调用量子测量的情况下对中介半量子密钥分布的三种攻击

半量子密钥分发是量子密钥分发的一个非常有趣的新分支。当一个或多个参与者被限制仅在量子计算的基础上操作量子状态时，可以实施该方法。最近，有人提出了一种不调用两个参与者的量子测量的中介半量子密钥分发协议。该协议允许两个没有复杂量子能力的“经典”参与者在不受信任的第三方下建立共享密钥。据称，该协议可抵抗多种众所周知的攻击。但是，本文首先指出，在不调用量子测量的情况下，对中介的半量子密钥分发协议存在三种攻击：“测量攻击，修改攻击和集体攻击”。通过提议的攻击，
