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.

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. A simulation IBM Cloud Platform confirmed feasibility our security analysis further demonstrated STP both were unable learn anything about individual inputs. other protocols, solution offers superior performance in terms

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.

In this paper, we introduce a quantum private comparison (QPC) protocol designed for two players to securely and privately assess the equality of their information. The utilizes four-particle cluster states prepared by semi-honest third party (TP), who strictly adheres without deviation or collusion with any participant. TP facilitates enabling users encode information through bit-flip phase-shift operators applied received sequences. Once is encoded, sequences are returned TP, can derive results accessing details This design ensures correctness, privacy, fairness throughout process. QPC robust against both external threats participant attacks due incorporation decoy-state method key distribution techniques. Additionally, employs unitary operations Bell-basis measurements, enhancing its technical feasibility practical implementation. Notably, proposed achieves qubit efficiency up 50%. efficiency, combined strong security features, establishes as promising solution comparisons within realm cryptography.

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.
