In today Internet era, confidential information transmitted over an insecure channel. With the
significant development in the area of quantum computing, there is a need for unconditional …

Secure communication has achieved a new dimension with the advent of the schemes of
quantum key distribution (QKD) as in contrast with classical cryptography, quantum …

The application of semi‐quantum conception can provide unconditional secure
communication for communicators without quantum capabilities. A semi‐quantum key …

To achieve unconditional security through quantum key distribution (QKD), users involved in
key distribution first need to authenticate each other. Classical identity authentication …

This paper proposes an efficient semi-quantum private comparison protocol (SQPC) using
single photons, which allows two classical participants to securely compare the equality of …

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 …

Semi-quantum communication, a model introduced by Boyer et al.(Phys Rev Lett 99:
140501, 2007), involves the use of fully quantum users and semi-quantum, or “classical” …

Private comparison is a primitive for many cryptographic tasks, and recently several
schemes for the quantum private comparison (QPC) have been proposed, where two users …

In this paper, we propose a two-party semiquantum summation protocol, where two classical
users can accomplish the summation of their private binary sequences with the assistance of …

In this paper, a novel semiquantum private comparison (SQPC) protocol based on single
kind of Bell states is proposed, which allows two classical parties to judge the equality of …
