“…In this paper, we proposed two authenticated QKD protocols based on GV95 communication system [43]. Specifically, we first present an interim scheme by mixing the process of GV95-QKD protocol [44] and GV95-QIA protocol [43] randomly. However, through security analysis, we find that the mixing scheme is insecure against a man-in-the-middle attack.…”

“…The security of GV95-QIA protocol and GV95-QKD protocol has been proved in Refs. [43], [44] respectively, therefore, the main task of this part is to analyze whether the adversary can discriminate the process of QIA and QKD. Here we first analyze whether the adversary can discriminate the two processes when he intercepts a single photon in the mixing scheme.…”

“…However, some of the existing QIA protocols have not implemented the function of key update. For example, the QIA protocol based on GV95 system (GV95-QIA) [43], [44] cannot update the authentication key securely, although the authors claim that the participants can perform GV95-QKD protocol to update and extend authentication keys after authentication of GV95-QIA protocol. The reason is that the adversary can wait until the legitimate communicators complete the QIA protocol, and then perform man-in-the-middle attack during the QKD protocol.…”

As is known, quantum key distribution (QKD) can provide information-theoretic security under some preconditions, one of which is that the identity of each participant has been authenticated. And quantum identity authentication (QIA) can achieve this precondition effectively. However, the adversary still can implement man-in-the-middle attacks on QKD protocols in some situations, such as the protocol in [Quant. Inf. Process, 18, 137 (2019)]. In the above paper, the authors claimed that, after their QIA protocol based on GV95 system (GV95-QIA protocol), the participants could perform GV95-QKD protocol to update and extend the authentication keys. However, this method is not secure in the sense that the adversary could wait for the participants to complete GV95-QIA protocol and then perform the man-in-themiddle attack on the QKD process. In this paper, we solve this problem by mixing GV95-QIA process and GV95-QKD process randomly. Specifically, two authenticated QKD protocols are proposed based on the above idea. The proposed protocols can be used to provide secure identity authentication to GV95-QKD protocol, and also can be used to extend the authentication keys for GV95-QIA protocol.

Multipartite quantum secure direct communication (MQSDC) enables multiple message senders to simultaneously and independently transmit secret messages to a message receiver through quantum channels without sharing keys. Existing MQSDC protocols all assume that all the communication parties are legal, which is difficult to guarantee in practical applications. In this study, a single‐photon based three‐party QSDC protocol with identity authentication is proposed. In the protocol, the message receiver first authenticates the identity of two practical message senders. Only when the identity authentication is passed, the legal message senders can encode their messages by the hyper‐encoding technology. In theory, two bits of messages can be transmitted to the message receiver in a communication round. The protocol can resist the external attack and internal attack, and guarantee the security of the transmitted messages and the identity codes of each legal message sender. The secret message capacity of the protocol is simulated with two‐decoy‐state method. The maximal communication distance between any two communication parties can reach ≈31.75 km with weak signal and decoy state pulses. The three‐party QSDC protocol can be extended to a general MQSDC protocol and has important application in the further practical MQSDC field.
