Abstract

Modern information security measures have changed as a result of the quick development of quantum computing and communication technologies. As computing power increases, traditional steganography methods are more susceptible to quantum attacks. By using quantum mechanical features like superposition, entanglement, and quantum error-correcting algorithms to safely hide data, quantum steganography shows promise as a solution. Quantum steganography is an advanced cyber security method that offers full secrecy from either classical or quantum hacking. Using quantum-resistant methods for secure (biometric) transmission, anti-spoofing, and privacy-preserving authentication, this work presents a quantum steganography technique that expands upon the benefits of digital imaging's Novel Enhanced Quantum Representation (NEQR). Our research and testing have demonstrated that our method is secure against a variety of attacks and provides defense against present and potential dangers while preserving the steganography characteristics of capacity and imperceptibility, making it one of the greatest choices for transmitting confidential data.

Quantum steganography for secure data transmission

Gabriela Mogos, Ho-Pun Lam

Abstract Quantum steganography is an advanced method of hiding information within quantum systems, leveraging the unique properties of quantum mechanics-such as superposition, entanglement, and the no-cloning theorem-to achieve unbreakable secrecy. Quantum steganography provides perfect secrecy against both classical and quantum hacking, making it a cutting-edge technology in cybersecurity. This paper introduces a quantum steganography technique that builds on the advantages of of Novel Enhanced Quantum Representation (NEQR) of digital imaging and integrates quantum-resistant solutions for secure (biometric) transmission, anti-spoofing, and privacy-preserving authentication. Our analysis and experiments have shown that our approach is robust against several types of attacks, and offers protection against both current and future threats while maintaining the steganographic property of imperceptibility and capacity, making it one of the best options for secret information transmission.

Quantum Steganography: Hiding Secret Messages in Images using Quantum Circuits and SIFT

Hassan Jameel Azooz, Khawla Ben Salah, Monji Kherallah +1 more

In today’s era of escalating digital threats and the growing need for safeguarding sensitive information, this research strives to advance the field of information concealment by introducing a pioneering steganography methodology. Our approach goes beyond the conventional boundaries of image security by seamlessly integrating classical image processing techniques with the cutting-edge realm of quantum encoding. The foundation of our technique lies in the meticulous identification of distinctive features within the cover image, a crucial step achieved through the utilization of SIFT (Scale-Invariant Feature Transform). These identified key points are further organized into coherent clusters employing the K-means clustering algorithm, forming a structured basis for our covert communication process. The core innovation of this research resides in the transformation of the concealed message into a NEQR (Novel Enhanced Quantum Representation) code, a quantum encoding framework that leverages the power of quantum circuits. This transformative step ensures not only the secrecy but also the integrity of the hidden information, making it highly resistant to even the most sophisticated decryption attempts. The strategic placement of the quantum circuit representing the concealed message at the centroids of the clusters generated by the K-means algorithm conceals it within the cover image seamlessly. This fusion of classical image processing and quantum encoding results in an unprecedented level of security for the embedded information, rendering it virtually impervious to unauthorized access. Empirical findings from extensive experimentation affirm the robustness and efficacy of our proposed strategy.

Quantum Key Distribution With Steganography: A Systematic Review of Hybrid Security Frameworks for Postquantum Cryptography

Md. Farhan Shahriyar, Md Abdulla Al Mamun

Quantum computing threatens classical cryptography and the convergence of quantum key distribution (QKD), and steganography offers an unconditionally secure hybrid approach for postquantum communication. QKD ensures provable secrecy via quantum mechanics, while steganography conceals the existence of communication providing stealth and plausible deniability. This systematic review explores integrated frameworks that combine QKD with classical and quantum steganographic techniques to enhance confidentiality, integrity, and undetectability. The study categorizes existing hybrid models and evaluates their performance using metrics such as quantum bit error rate (QBER), entropy, and imperceptibility. It examines quantum steganographic protocols including quantum LSB, entangled‐state hiding, and covert key transmission, analyzing their resilience against quantum noise and steganalysis. Despite promising simulation tools and real‐time QKD implementations, challenges remain in scalability, interoperability, and formal security guarantees. This review identifies key limitations in current systems and highlights future directions for developing robust, scalable, and stealth‐aware quantum–classical security frameworks. To the best of current knowledge, this is the first systematic synthesis of hybrid QKD–steganography frameworks offering a novel taxonomy and critical analysis to advance secure communication infrastructures in the postquantum era.
