“…[38,39] In recent few years, QSDC has developed rapidly in both theory and experiment. [40][41][42][43][44][45][46][47][48][49][50][51][52][53][54] In theory, DI-QSDC and MDI-QSDC were put forward, which can largely enhance QSDC's security under practical experimental condition. [41][42][43][44] In 2021, Long and Zhang adopted the mask-ing technology in QSDC to increase its capacity, communication distance, and tolerable error rate greatly.…”

The one-step quantum secure direct communication (QSDC)(Sci. Bull. 67, 367 (2021)) can effectively simplify QSDC’s operation and reduce message loss. For enhancing its security under practical experimental condition, we propose two measurement-device-independent (MDI) one-step QSDC protocols, which can resist all possible attacks from imperfect measurement devices. In both protocols, the communication parties prepare identical polarization-spatial-mode two-photon hyperentangled states and construct the hyperentanglement channel by hyperentanglement swapping. The first MDI one-step QSDC protocol adopts the nonlinear-optical complete hyperentanglement Bell state measurement (HBSM) to construct the hyperentanglement channel, while the second protocol adopts the linear-optical partial HBSM. Then, the parties encode the photons in the polarization degree of freedom and send them to the third party for the hyperentanglement-assisted complete polarization Bell state measurement. Both protocols are unconditionally secure in theory. The simulation results show the MDI one-step QSDC protocol with complete HBSM attains the maximal communication distance of about 354 km. Our MDI one-step QSDC protocols may have application potential in the future quantum secure communication field.

“…In addition to QKD, Quantum secure direct communication (QSDC) is an important primitive of quantum cryptography [5,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31]. The key difference between QKD and QSDC is that QKD generates random keys between communication parties, whereas QSDC directly transmits secret information.…”

Quantum Secure Direct Communication (QSDC) is an important branch of quantum cryptography, which enable secure transmission of messages without prior key encryption. However, traditional quantum communication protocols rely on the security and trustworthiness of the devices employed to implement the protocols, which can be susceptible to attacks. Device-independent (DI) quantum protocols, on the other hand, aim to secure quantum communication independent of the devices used by leveraging fundamental principles of quantum mechanics. In this research paper, we introduce the first DI-QSDC protocol that includes user identity authentication to establish the authenticity of both sender and receiver before message exchange. We also extend this approach to a DI Quantum Dialogue (QD) protocol where both parties can send secret messages upon mutual authentication.

“…Quantum cryptography based on the principle of quantum mechanics rather than the computational complexity of solving mathematical problems has a considerable advantage of security over classical cryptography. Since the first quantum cryptographic protocol was proposed by Bennett and Brassard [1] and its unconditional security was proved in 1984, numerous quantum cryptographic protocols have been proposed to solve various cryptographic tasks, such as quantum key distribution (QKD), [1][2][3][4] quantum key agreement (QKA), [5][6][7] quantum secret sharing (QSS), [8][9][10][11] quantum secure direct communication (QSDC), [12][13][14] and quantum private query (QPQ). [15][16][17][18] Secure multiparty computation (SMC) aims to calculate a function in a distributed network of mutual distrust without disclosing the raw content of each party's private inputs.…”

In this paper, by using swap test, a quantum private comparison (QPC) protocol of arbitrary single qubit states with a semi-honest third party is proposed. The semi-honest third party (TP) is required to help two participants perform the comparison. She can record intermediate results and do some calculations in the whole process of the protocol execution, but she cannot conspire with any participants. In the process of comparison, TP cannot get two participants' private information except the comparison results. According to the security analysis, the proposed protocol can resist both outsider attacks and participant attacks. Compared with the existing QPC protocols, the proposed one does not require any entanglement swapping technology, and it can compare two participants' qubits by performing swap test, which is easier to implement with current technology. Meanwhile, the proposed protocol can compare secret integers. It encodes secret integers into the amplitude of quantum state rather than transfer them as binary representations, and the encoded quantum state is compared by performing swap test. Additionally, the proposed QPC protocol is extended to the QPC of arbitrary single qubit states by using multi-qubit swap test.
