This study first defined a new privacy protection problem, namely, quantum secure multiparty logical XOR (SMC_ XOR), and then designed corresponding quantum circuits where multiple participants could jointly calculate the logical XOR of their respective private bits. The proposed quantum SMC_XOR protocol can ensure unconditional security, i.e., information-theoretical security. Furthermore, we designed a grouping strategy to reduce communication complexity and presented an improved quantum SMC_XOR protocol. The improved quantum protocol is used to secure communication in metropolitan area networks, allowing two remote users to securely transmit confidential messages. Finally, we verified the correctness and feasibility of the proposed quantum SMC_XOR protocol by conducting circuit simulations on the IBM quantum system in Qiskit.

“…Subsequently, due to its ability to resist quantum attacks in information protection and secure communication, quantum cryptography has attracted high attention and achieved rapid development. In recent years, multiple branches of quantum cryptography have been extensively studied, such as quantum secret sharing (QSS) [4,5], quantum signature (QS) [6][7][8], quantum key distribution (QKD) [9,10], quantum secure direct communication (QSDS) [11,12],and so on.…”

With the rapid development of computer and internet technology, quantum signature plays an extremely important role in modern secure communication. Quantum homomorphic aggregate signature, as an important guarantee of quantum signature, plays a significant role in reducing storage, communication, and computing costs. This article draws on the idea of quantum multi-party summation and proposes a quantum homomorphic aggregate signature scheme based on quantum Fourier transform. Our scheme uses n-particle entangled states as quantum channels, with different particles of each entangled state sent separately. This ensures secure transmission of signatures and messages with fewer entangled particles during transmission, further improving the efficiency of quantum signatures. Meanwhile, our scheme generates private keys for each participating party by randomly constructing key generation matrixes. Different signers perform quantum Fourier transforms and basis exchange operations on entangled particles based on different messages and private keys to generate signatures. In addition, the aggregator does not need to measure and verify the signature particles after receiving signatures from different signers, and the group addition operation process has additive homomorphism. Security analysis shows that our scheme has unforgeability, non-repudiation, and can resist various attacks such as entanglement measurement attacks, intercept-resend attacks, private key sequence attacks, and internal attacks by aggregator.

“…AQC is an important branch of quantum communication. AQC, along with other branches of quantum communication such as quantum key distribution [17][18][19][20], quantum secure direct communication [21][22][23][24][25], and quantum teleportation [26,27], plays a significant role in ensuring secure information transmission. In addition, researchers have proposed various other anonymous quantum cryptographic protocols, such as quantum anonymous voting [28][29][30], quantum anonymous ranking [31][32][33], and so on.…”

Anonymous quantum communication (AQC) enables the secure transmission of classical and quantum messages while preserving the anonymity of the sender, receiver, or both. Qudits, quantum states with more advantages than qubits in terms of information transmission rate and eavesdropping detection, offer promising capabilities. In this paper, we propose a verifiable AQC (VAQC) protocol utilizing $d$-level single-particle states, establishing anonymous entanglement between a public sender and an anonymous receiver. By using quantum teleportation, the public sender can transmit private information to his/her chosen anonymous receiver. The verifiable function of the proposed protocol guarantees the legitimacy of all participants' identities and verifies the correctness of the anonymous entanglement. Furthermore, we demonstrate that the proposed VAQC protocol satisfies the requirements of correctness, anonymity, and security. The proposed VAQC protocol exhibits extensibility and can be extended to enable private communication between an anonymous sender and an anonymous receiver, as well as anonymous entanglement among multiple participants. This work lays the foundation for practical applications in achieving $d$-level anonymous entanglement and anonymous transmission of qudits.
