Abstract

In the digital, networked and visual age, the image has become the key medium for conveying information and knowledge. Image security has attracted increasing attention as the operation, sharing and communication in various fields. However, with the widespread use of networks, the security of image transmission faces serious challenges, including unauthorized access, tampering, and interception by malicious attackers. Traditional cryptographic methods play a limited role in image security in the cyber age. With the development of quantum computing and quantum communication, quantum image encryption has emerged, and it fully protects the image security from the perspective of quantum mechanics. When the image is encrypted in the quantum state, due to the quantum properties , quantum image encryption becomes extremely secure. As a result, it is impossible for classical computer technology to decode the encrypted images. Quantum Image Encryption not only protects against image theft and tampering but also enables secure image transmission.In this paper, we present a method for quantum encryption of color images based on NCQI representation and modification of RGB pixel positions and their values. In several steps, using NCQI representation and some quantum logic gates, we can identify the quantum state of the image and modify the RGB pixel values and positions. By calculating several parameters, we conclude this study with a statistical evaluation that proves the effectiveness and strength of our method. This research contributes to the burgeoning field of quantum cryptography by introducing a novel method tailored specifically for color image encryption, thereby advancing the capabilities of quantum secure communication protocols.

A Gray Image Quantum Encryption using GNEQR Representation

Achraf Abdelghafour Zemate, Moulay Brahim Sedra

In the digital era, characterized by extensive online data exchange, information security has become a priority. While traditional encryption methods have proven effective in protecting data transfers, the advent of advanced quantum computing has increased susceptibility to security breaches. Quantum encryption provides a revolutionary solution to this problem by using quantum mechanics principles to establish algorithms that are impermeable to decryption. Using these quantum properties, cryptographic protocols are developed to provide superior security, unlike traditional encryption methods. The image plays an important role in transmitting information in all areas. Therefore, quantum image encryption methods are specifically designed to counter the potential risks posed by quantum computers, which can compromise conventional encryption protocols. This ensures the preservation of data security despite advances in quantum computing technology. In addition, quantum image encryption improves data transmission efficiency by establishing secure communication channels using quantum stats, thereby reducing the need for bandwidth and improving transmission speed. This paper proposes a new method of quantum encryption based on GNEQR representation and the modification of pixel values and positions in an image. After converting the image into a quantum form, we applied an algorithm to modify the values and positions of the pixels using a succession of quantum gates. We concluded this study with a statistical analysis showing the robustness of our quantum image encryption method.

A quantum image encryption scheme based on quantum Arnold transform and hyper 5D chaotic system

Lishi Liu, Chenhao Yin, Yumin Dong

In the wake of the information security era, ensuring the privacy, accuracy, and reliability of images has become imperative. In this paper, a quantum image encryption method combining quantum Arnold transform and a hyper 5D chaotic system is devised. Furthermore, first, a nonlinear color quantization model (NCQI) is used to convert digital images in standard RGB format into quantum color images. Then, based on the size of the converted quantum color image, the corresponding encryption key is generated using the hyper 5D chaotic system. In the encryption stage, we use the key to encrypt the converted quantum color image. This process entails two principal steps: First, we use quantum Arnold transform to scramble the pixel positions in the image and, subsequently, diffuse the pixel values through a carefully designed cyclic shift strategy to achieve the preliminary encryption of the image. To further strengthen the encryption security, we use a quantum rotation gate to perform quantum rotation transformation on the color channel of each pixel point in the encrypted image separately. These well-designed encryption processes, in succession, significantly enhance the security of the image. This paper provides the corresponding quantum circuit design and validates both the efficacy and security of the quantum image encryption scheme through simulation experimental results.

Quantum RGB Image Encryption based on Bit-planes and Logistic Map

Saeed Basiri, Laleh Farhang Matin, Mosayeb Naseri

Abstract Data encryption is one of the main factors in their transmission. In this paper, we have described an algorithm for color image encryption, some quantum encryption and image scrambling operations will be performed based on bitplane representation of quantum images (BRQI). Next, the image created using the logistic map (key image) is blended with the output of the first step, which was possible with the help of a quantum comparator circuit. Finally we create a secure image as the output of the encryption algorithm. Experiments with simulation and analysis of parameters such as entropy and correlation coefficient of adjacent pixels in three main positions show that the proposed algorithm has been very efficient and effective in securing and encrypting color images.
