In response to rising cyber threats and the limitations of traditional security, this project proposes a hybrid framework combining quantum cryptography and text-based steganography for secure and concealed communication. Using the BB84 Quantum Key Distribution (QKD) protocol, a secure quantum key is established and extended with SHA-256 to encrypt a secret message via XOR operations. The encrypted data is embedded into a cover text using three steganographic techniques: case-based, zero-width, and color-based methods, the latter including double-color and double-color overlay variants. The techniques are evaluated on embedding efficiency, payload capacity, entropy, and deviation percentage. Among them, double-layer color-based steganography demonstrates superior performance, achieving up to 6 bits/symbol and 95% efficiency, with minimal error and high integrity. The system is implemented using Qiskit and HTML rendering, validating its practical feasibility. This dual-layer security model ensures confidentiality and invisibility, offering a robust, quantum-enhanced approach to secure communication in sensitive applications.
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.
We are building a highly secure way of sending messages by combining the use of Quantum Key Distribution (QKD) to produce encryption keys and encrypting messages with a variant of AES-256 (a substitution cipher) and Least Significant Bit (LSB) steganography or hiding them in images. We are employing the BB84 protocol to produce these keys based on the quantum properties of the photonic (light) particles; we can detect any third parties attempting to intercept the key and measure it by the Quantum Bit Error Rate (QBER). Once we have produced a secure key, we then use it to encrypt the actual message with AES-256, and we hide that in a digital image (the cover image) with LSB steganography. Thus, if a third party were to capture the Stego image (the digital image containing the hidden encrypted message), they would not be able to decrypt the hidden message without the key that was produced using quantum cryptography. An analytics dashboard monitors the success of the key generation, the QBER value, and other performance metrics, giving a high degree of transparency and trustworthiness of the whole process.
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.
In today’s digital era, where sensitive data is frequently transmitted over email, ensuring secure communication has become a pressing concern. This paper aims to integrate the principles of quantum cryptography to redefine email security. Quantum Key Distribution (QKD) leverages the laws of quantum mechanics to create cryptographic keys that are virtually unbreakable, offering an unprecedented level of protection against modern cyber threats. Historically, email security evolved alongside the rise of the internet. Initial systems lacked robust protection, relying on basic passwords or unencrypted messages. The introduction of Secure/Multipurpose Internet Mail Extensions (S/MIME) and Pretty Good Privacy (PGP) marked significant advancements, providing encryption for email content. However, traditional encryption techniques depend heavily on the computational complexity of algorithms, making them vulnerable to advances in processing power, particularly with the advent of quantum computing. Traditional email security systems have several limitations. While methods like TLS and end-to-end encryption mitigate some risks, they cannot guarantee long-term security against quantum-level decryption techniques. The motivation for this paper stems from the need to address these vulnerabilities and enhance trust in digital communication systems. Increasingly sophisticated cyberattacks, data breaches, and the potential threats posed by quantum computing have inspired the development of a revolutionary solution that combines quantum cryptography with email systems. The goal is to proactively safeguard sensitive communication against evolving threats, ensuring data integrity and confidentiality. The proposed system integrates QKD to secure email communications. By generating encryption keys based on quantum states, it ensures that any attempt to intercept the keys is detectable. This system also encrypts email content and attachments with these quantum-generated keys, providing enhanced security against interception and decryption attempts. With features like quantum-encrypted file storage and robust authentication mechanisms, this system sets a new standard for email security.
