Abstract

Steganography is the art and science of hiding the fact that communication is taking place. Steganographic systems can hide messages inside of images or other digital objects. To a casual observer inspecting these images, the messages are invisible. The security of a classical steganographic system relies on the secrecy of the encoding system. Once the encoding system is known, the steganographic system is defeated. However, modern steganography should be detectable only if secret information is known, namely, asecret key. Because of their invasive nature, steganographic systems leave detectable traces within a medium's characteristics. This allows an eavesdropper to detect modified media, revealing that secret communication is taking place. Although the secret content is not exposed, its existence is revealed, which defeats the mainpurpose of steganography. This work has as purpose to expand the field of applicability of the steganography from the classical informatics to the quantum one.

Hide Secrets Using the Power of Quantum Computers

Gabriela Mogos

Secret communication is everywhere around us today. Cryptography is being used to encrypt messages so that they can be read only by someone who has the key.Combining the art of steganography with the powers of computers has brought a method of hiding information to a whole new level. Steganography hides messages so that their very existence is undetectable. The idea of embedding some information within a digital media, in such a way that the inserted data are intrinsically part of the media itself, has aroused a considerable interest in different fields. This work has as a purpose to expand the field of applicability of the embedded information within a digital media from the classical informatics to the quantum one.

PREREQUISITES FOR THE ESTABLISHMENT OF A QUANTUM STEGANOGRAPHY COMMUNICATION

Veselka Stoyanova

Several approaches and techniques exist to make communication via the internet secure, one of these approaches is steganography. Computer steganography can be defined as a method of hiding data in cover media so that others are not aware of its existence. Quantum computers, built on the principles of quantum physics, have introduced new possibilities for researchers in security and computer science. This paper explores the fundamentals of quantum computing, its achievements, and the challenges and future prospects it presents in the field of cryptography and steganography. Quantum computers give us a new approach to different kinds of complicated problems in security fields by creating multi-state computing spaces. The article deals with the steganography system which hides text inside images and after that realize quantum communication. The secret message is hidden in the cover image using Least Significant Bit (LSB) algorithm. The paper proposes an information transmission scheme with a quantum channel enabled. Quantum key distribution (QKD) is a secure communication method that implements a cryptographic protocol involving components of quantum mechanics.

Hybrid Quantum Steganographic Techniques for Secure Data Concealment in Quantum Communication

Sujata Jagtap, Vaishali Jagtap

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 over noiseless channels: Achievability and bounds

Chris Sutherland, Todd A. Brun

Quantum steganography is the study of hiding secret quantum information by encoding it into what an eavesdropper would perceive as an innocent-looking message. Here we study an explicit steganographic encoding for Alice to hide her secret message in the syndromes of an error-correcting code, so that the encoding simulates a given noisy quantum channel. We calculate achievable rates of steganographic communication over noiseless quantum channels using this encoding. We give definitions of secrecy and reliability for the communication process, and with these assumptions derive upper bounds on the amount of steganographic communication possible and show that these bounds match the communication rates achieved with our encoding. This gives a steganographic capacity for a noiseless channel emulating a given noisy channel.
