• Abstract: In this paper, we propose a novel semiquantum private comparison (SQPC) protocol of size relationship based on d-level single-particle states. The designed protocol can compare the size relationship of different privacy messages from two classical users with the help of a semi-honest third party (TP), who is permitted to misbehave on her own but cannot be in collusion with anyone else. The correctness analysis shows that this protocol can gain correct comparison results. The security analysis turns out that this protocol can resist famous outside attacks and participant attacks. Moreover, this protocol can guarantee that TP does not know the accurate comparison results. Compared with the only existing SQPC protocol of size relationship (Quantum Inf. Process. 20:124 (2021)), this protocol takes advantage over it on the aspects of initial quantum resource, TP's measurement operations and TP's knowledge about the comparison results.

  We propose a new protocol of measurement-device-independent quantum secure direct communication and quantum dialogue employing single basis, i.e., Bell basis as decoy qubits for eavesdropping detection. Our protocols leverage fundamentally distinct resources to close the security loopholes linked to measurement devices, while also effectively doubling the distance for secure direct message transmission.

The proposed MQPC protocol can be used in the strange user environment, because there are not any communication and pre-shared key between each pair of users.

  Quantum key distribution (QKD) allows the establishment of common cryptographic keys among distant parties. Recently, a QKD protocol that circumvents the need for monitoring signal disturbance, has been proposed and demonstrated in initial experiments. We derive the security proofs of the round-robin differential phase-time-shifting protocol in the collective attack scenario. Our results show that the RRDPTS protocol can achieve higher secret key rate in comparison with the RRDPS, in the condition of high quantum bit error rate.
