Security of NEQR Quantum Image by Using Quantum Fourier Transform with Blind Trent

Mustafa Engin Şahin, Murat İhsan Yılmaz

Published Jan 31, 2018• 2 citations

Abstract

In this study, the security of Novel Enhanced Quantum Representation (NEQR) of quantum images are suggested by using the Quantum Fourier Transform (QFT) with blind trent. In the protocol, QFT and keys are used to share signature with recipients. So all members know only their signature information which are encrypted output of the QFT. This improves the security of the protocol. In addition, the security of the protocol is provided by using reorder QFT output qubits with permutation of the blind trent. The security analysis expresses security of the transfer of the image with effective secret key usage.

Quantum Group Proxy Digital Signature based on Quantum Fourier Transform by Using Blinded and Non Blinded Trent

Ä°hsan Yilmaz

In this study, quantum proxy group signature protocol based on the Quantum Fourier Transformation(QF T) is suggested. In this protocol, QF T is used to share signature with group members. So all proxy group members know only their part of the signature information which are encrypted output of the QF T. This improves the security of the protocol. In addition, the security of the quantum proxy group signature is provided by using reorder QF T output qubits with permutation of the Trent,blinded and nonblinded . The security analysis expresses higher efficiency, effective secret key usage and security of the proposed protocol.

Secure Transmission of 3D-QRMW Quantum Images via Quantum Fourier Transform in Blind Cloud

Omer Dogan, İhsan Yılmaz

This study explores three-dimensional multi-channel quantum image representation model (3D-QRMW) which can be used in many fields such as three-dimensional medical imaging, atomic imaging, and infrared images. Quantum images are transmited between participants by Quantum Fourier Transform (QFT) in which output qubits are reordered by blind Cloud with permutation. Also key with length K=16N is applied to share signature for recipients. This allows all members to know only their signature information. Security analyzes show that quantum images in the model of 3D-QRMW are transmitted safely. Keywords : 3D quantum image, Security of 3D quantum image, Blind Cloud, Quantum Fourier.

Blind quantum computation for quantum Fourier transform on Bell states

Xiaoqian Zhang

It is called blind quantum computation(BQC) that a client who has limited quantum technologies can delegate her quantum computing to a server who has fully-advanced quantum computers. But the privacy of the client's quantum inputs, algorithms and outputs is still a challenge. To realize a secure BQC, we mainly study how to hide quantum fourier transform (QFT) performed on Bell states. In this paper, three cases are considered as follows. For the first case, we design primary BQC protocols of QFT performed on qubits 12 of belonging to $\{|ϕ^\pm\rangle_{12},$ $|ψ^\pm\rangle_{12}\}$ with relevant circuits. To strengthen security, we construct enhanced BQC protocols of QFT performed on qubits 13 of any two Bell states $|ξ\rangle_{12}\otimes|θ\rangle_{34}$ with relevant quantum circuits. Featured the property of stronger security, we give generalized BQC protocols of QFT performed on qubits 13 and 24 of any two Bell states with relevant quantum circuits respectively. At last, we analyze and prove the blindness and correctness.

A Strong Blind Quantum Signature Protocol Based on Secret Sharing

Xiamu Niu

A strong blind quantum signature protocol was presented based on secret sharing.In this protocol,the three pho-tons of each GHZ(Greenberger-Horne-Zeilinger)triplet are delivered to the message owner Alice,signatory Trent and verifier Bob respectively.Alice measures her photon to blind her message while Trent measures his photon to sign the blinded message,and then Bob verifies the signature according to the measuring results of his photon under the relationship of GHZ states.However,Bob's ac-tions are restricted by the quantum fingerprints and the audit program.Our protocol ensures that the signature is blind and the mes-sage owner is untraceable.Moreover,its security was not influenced by the computational resource of attackers.

Quantum secure image encryption using hybrid QTRNG and QPRNG

T. S. Gururaja, Padmapriya Praveenkumar

Secure image transmission has become critical in the emerging quantum computing landscape. This research introduces a hybrid key quantum encryption approach that combines Quantum True Random Number Generation (QTRNG) and Quantum Pseudo Random Number Generation (QPRNG) to enhance security and efficiency. The proposed Quantum Hybrid Random Number Generator (QHRNG) integrates entanglement-based true randomness with structured pseudo-randomness using Hadamard, controlled rotation and Clifford gates to generate high-entropy encryption keys. The generated Quantum keys are applied to encrypt grayscale images using the Novel Enhanced Quantum Image Representation (NEQR). The encryption process is strengthened by quantum bit-level scrambling and selective Quantum Fourier Transform. The proposed method is implemented on Qiskit’s Aer and Basic simulators and validated on IBM’s torino quantum hardware. Compared to standalone QTRNG and QPRNG methods, QHRNG consistently provides higher randomness and stronger security in noisy and noiseless environments. This work offers a robust and future-ready framework for quantum secure image encryption.
