Publisher

Abstract

The chapter provides a comprehensive overview of the evolving field of quantum steganography, highlighting its potential impact on information security in the age of quantum computing. Steganography, rooted in ancient practices, has traditionally concealed data within classical computing systems, but the emergence of quantum computing poses new challenges. Quantum steganography adapts classical principles to leverage the unique properties of quantum mechanics, employing quantum bits (qubits), superposition, and entanglement for secure data concealment. The abstract delves into the conceptual framework of a quantum steganography algorithm, emphasizing its complexity and the integration of quantum key distribution for enhanced security. The applications span secure communication, medical records, financial transactions, military defense, intellectual property protection, and more. Despite promising prospects, quantum steganography faces challenges such as quantum state fragility and hardware constraints, requiring ongoing research to unlock its full potential in safeguarding sensitive information.

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.
