“…For example, such an effort was made in [89] where a scheme of QIA was obtained by slightly modifying BB84 protocol of QKD. Lately, a counterfactual QKD scheme was modified to propose a scheme for QIA in [76]. Further, in the early work of Duï¿oeek et al a classical-quantum hybrid scheme of authentication was used where the quantum part was based on QKD.…”

“…Specifically, it allowed quantum Alice (Bob) to identify classical Bob (Alice). Another facet of modern quantum cryptography also found its place in the authentication protocol in this year when Liu et al introduced a QIA protocol [76] which can be used in the counterfactual QKD schemes. Zheng et al proposed a controlled QSDC (CQSDC) protocol with authentication [77] using five-qubit cluster state.…”

Secure communication has achieved a new dimension with the advent of the schemes of quantum key distribution (QKD) as in contrast to classical cryptography, quantum cryptography can provide unconditional security. However, a successful implementation of a scheme of QKD requires identity authentication as a prerequisite. A security loophole in the identity authentication scheme may lead to the vulnerability of the entire secure communication scheme. Consequently, identity authentication is extremely important and in the last three decades several schemes for identity authentication, using quantum resources have been proposed. The chronological development of these protocols, which are now referred to as quantum identity authentication (QIA) protocols, are briefly reviewed here with specific attention to the causal connection involved in their development. The existing protocols are classified on the basis of the required quantum resources and their relative merits and demerits are analyzed. Further, in the process of the classification of the protocols for QIA, it's observed that the existing protocols can also be classified in a few groups based on the [inherent computational tasks used to design the protocols. Realization of these symmetries has led to the possibility of designing a set of new protocols for quantum identity authentication, which are based on the existing schemes of the secure computational and communication tasks. The security of such protocols is also critically analyzed.

“…Therefore, in a secure combination of GV95-QKD protocol and GV95-QIA protocol, the two kinds of processes should be mixed randomly. In [45], Liu et al proposed a method of mixing the process of QIA into QKD. Their authenticated counterfactual QKD protocol mixes the process of the QIA protocol they proposed and the counterfactual QKD protocol in [46], and the combined processes can be used to extend the length of the authentication key.…”

“…This paper effectively solves the above problem through two characteristic methods. Specifically, we first present a scheme to mix the process of GV95-QIA protocol into GV95-QKD protocol randomly, which refers to the work of Liu et al in [45]. The purpose of mixing is to ensure that the adversary cannot discriminate between a QIA signal and a QKD signal so that he cannot attack the QKD process through bypassing the QIA process.…”

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.

“…Given the unique security of quantum secure communication, various quantum cryptography protocols [2][3][4][5] have been proposed; these include Quantum signature (QS) protocols [6][7][8][9][10] , Quantum key distribution (QKD) protocols [11][12][13] , Quantum identity authentication (QIA) protocols [14][15][16][17] , and Quantum secure direct communication (QSDC) protocols [18][19][20] . Based on these quantum communication protocols, several quantum payment protocols [21][22][23][24] have been designed.…”
