Based on d d-dimensional Bell states, a new semi-quantum private comparison protocol is
designed under the assistance of a semi-honest third party. Compared with the existing semi …

As an important branch of quantum secure multiparty computation, quantum private
comparison (QPC) has attracted more and more attention recently. In this paper, according …

In this paper, we successfully design the semi-quantum private comparison (SQPC) protocol
with the measure-resend characteristic by using two-particle product states as the initial …

In this paper, we propose two semi-quantum private comparison (SQPC) protocols based on
Bell states. With the help of a semi-honest quantum third party (TP), two classical users can …

We propose a feasible and efficient dynamic multiparty quantum private comparison
protocol that is fully secure against participant attacks. In the proposed scheme, two almost …

Two efficient quantum private comparison (QPC) protocols are proposed, employing single
photons and collective detection. In the proposed protocols, two distrustful parties (Alice and …

Quantum private comparison (QPC) represents a cryptographic approach that enables two
parties to determine whether their confidential data are equivalent, without disclosing the …

In this paper, a novel multi-party quantum private comparison protocol with a semi-honest
third party (TP) is proposed based on the entanglement swapping of d-level cat states and d …

Semi-quantum protocol allows users with only a small amount of quantum capabilities to
participate in quantum communication, which is conducive to the application of quantum …

Using the highly entangled six-qubit genuine state we present a quantum private
comparison (QPC) protocol, which enables two users to compare the equality of two bits of …
