A quantum private comparison (QPC) protocol enables two parties to securely compare their data without disclosing the actual values one another, utilizing mechanics maintain confidentiality. Many current QPC protocols mainly concentrate on comparing equality of information between users during a single execution, which restricts scalability. To overcome this limitation, we present an efficient aimed at evaluating groups in execution. This is achieved by leveraging entanglement correlations each particle four-particle cluster state. In our approach, encode using bit flip or phase shift operators sequence they receive, then sent back semi-trusted party determines whether secrets are equal and communicates results users. By employing method facilitating distributed transmission sequence, achieves qubit efficiency 50%. Security analyses reveal that neither external attacks nor insider threats can successfully compromise confidentiality data.

In this paper, we introduce a two-party quantum private comparison (QPC) protocol that employs single photons as resources and utilizes rotational encryption to safeguard the privacy of inputs. This enables two parties compare their data without disclosing any information beyond outcome comparison. The participants’ are encoded photons, which encrypted using method. These then transmitted semi-honest third party (TP), who conducts single-particle measurements determine if users’ equal subsequently announces results participants. By harnessing principles mechanics, ensure robust protection against potential eavesdropping participant attacks. contrast numerous existing QPC protocols rely on multi-qubit or d-dimensional states, our method exhibits superior efficiency practicality. Specifically, achieves qubit 50% by one bit classical information, easier prepare than states.

Quantum private comparison (QPC) represents a cryptographic approach that enables two parties to determine whether their confidential data are equivalent, without disclosing the actual values. Most existing QPC protocols utilizing single photons or Bell states considered highly feasible, but they suffer from inefficiency. To address this issue, we present novel protocol capitalizes on entanglement property of and local operations meet requirements efficiency. In proposed protocol, participants with inputs perform shared received semi-honest third party (STP). Afterward, modified qubits returned STP, who can then equality relay results participants.

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.
