Quantum private comparison (QPC) enables two users to securely conduct comparisons in a network characterized by mutual distrust while guaranteeing the confidentiality of their inputs. Most previous QPC protocols were primarily used determine equality information between users, which constrained scalability. In this paper, we propose protocol that leverages entanglement correlation particles four-particle cluster state. This can compare groups within one execution, with each group consisting users. A semi-honest third party (TP), who will not deviate from execution or conspire any participant, is involved assisting achieve comparisons. Users encode inputs into specific angles rotational operations performed on received quantum sequence, then sent back TP. Security analysis shows both external attacks and insider threats are ineffective at stealing data. Finally, our some previously proposed protocols.

Abstract In this paper, we propose a novel semiquantum private comparison (SQPC) protocol based on Bell states, which enables one quantum user and classical to compare the equality of their inputs with help semi-honest third party (TP). TP is assumed be in sense that she may take all possible attacks steal users’ except conspiring anyone. The security analysis validates our can resist not only from internal participants but also an external eavesdropper. Besides, asks perform basis measurements does need entanglement swapping; it releases conducting having memory. Moreover, advantage over previous SQPC protocols states qubit efficiency. Finally, generalized into its counterpart collective-dephasing noise channel.

Abstract Secure semi-quantum summation entails the collective computation of sum private secrets by multi-untrustworthy and resource-limited participants, facilitated a quantum third-party. This paper introduces three protocols based on single photons, where eliminating need for classical users to possess measurement capabilities. Two-party protocol 1 2 are structured upon different models: star ring, respectively. The security analysis extensively evaluates protocols’ resilience against outside inside attacks, demonstrating asymptotically secure. Protocol 3 extends two-party multi-party scenarios, broadening its applicability. Comparison reveals reduction in workload compared previous similar protocols, correctness visually validated through simulation Qiskit.

Abstract Semi-quantum secret sharing facilitates the of private data between quantum users and ‘classical’ with limited capabilities, thereby lowering barrier to utilizing technology. However, most current semi-quantum protocols are confined ideal environments two-party scenarios. In this paper, we design two collective noise-resistant multi-party based on decoherence-free states address potential noise interference during transmission. These use as information carriers for interaction exhibit strong resilience both internal external threats. We also conduct simulation experiments using IBM Qiskit verify stability feasibility in noisy environments. The results these underscore robustness protocols, particularly presence noise.

Abstract Semi-quantum private comparison allows multiple ‘classical’ users who have restricted quantum capabilities to compare their data with the assistance of a third party. In this work, we propose novel dynamic semi-quantum protocol using circular transmission mode along d -dimensional single-particle states. The enables size relations among several users, while party can only determine relative sizes without accessing users’ secret information. Security evaluations demonstrate that designed withstands typical external and internal attacks. Compared previous works, offers improvements: first, it supports addition or removal enhancing applicability in practical scenarios; second, eliminates need for pre-shared keys, reducing resource consumption; third, avoids use high-dimensional multi-particle entangled states, thereby feasibility implementation. Therefore, proposed may more potential compared protocols.
