Ensuring confidentiality and privacy is critical when it comes to sharing images over unsecured networks such as the internet. Since widely used and secure encryption methods, such as AES, Twofish, and RSA, are not suitable for real-time image encryption due to their slow encryption speeds and high computational requirements, researchers have proposed specialized algorithms for image encryption. This paper provides an introduction and overview of the image encryption algorithms and metrics used, aiming to evaluate them and help researchers and practitioners starting in this field obtain adequate information to understand the current state of image encryption algorithms. This paper classifies image encryption into seven different approaches based on the techniques used and analyzes the strengths and weaknesses of each approach. Furthermore, this paper provides a detailed review of a comprehensive set of security, quality, and efficiency evaluation metrics for image encryption algorithms, and provides upper and lower bounds for these evaluation metrics. Finally, this paper discusses the pros and cons of different image encryption approaches as well as the suitability of different image encryption approaches for different applications.

Motivated by the pursuit of both encryption efficiency and security, this paper presents a symmetric color image encryption algorithm using a novel cross–plane joint scrambling–diffusion method. To provide high–strength security, the color planes are firstly spliced horizontally and then vertically to be adequately encrypted by the joint scrambling–diffusion method. Therefore, minor changes in any pixel can cross every color plane that significantly influences the final cipher image. To achieve fast encryption speed, all employed chaotic systems have simple structures but robust properties to rapidly generate high–quality pseudorandom sequences. Additionally, the joint scrambling–diffusion method is vectorized to handle pixels in parallel for satisfactory execution efficiency. Security tests demonstrate the outstanding security performance of the proposed algorithm, with correlation coefficients and entropies of cipher images being close to 0 and greater than 7.99, respectively, and results of NPCR and UACI tests being similar to ideal cipher images, which can resist statistical, differential, exhaustive, and even chosen ciphertext/plaintext attacks. Moreover, because of the O(4W + 4H) time complexity of the novel scrambling–diffusion method, even a color image with a size of 1024 × 1024 only costs 0.26 s to be encrypted. Hence, the proposed algorithm can satisfy the efficiency and security requirements of color image encryption.

“…In the current era of rapid development of the Internet, there are a large number of images being delivered and processed in the network. This can easily lead to the disclosure of personal privacy and the threat of information security, so it is essential to encrypt and protect images transmitted on the Internet to maintain network information security [2]. Image data is different from general data.…”

On the basis of using quantum NEQR (novel enhanced quantum representation of digital image) to display images, a dual chaos system based on quantum logistic mapping is proposed to encrypt quantum images to ensure the security of quantum image transmission. The encryption algorithm is based on quantum logistic mapping and Chen chaos system to generate chaotic sequences, and uses quantum rotation gate operations to rotate and transform each pixel of the quantum image to achieve the effect of image encryption. Traditional quantum image encryption usually uses classical randomly generated sequences to construct the encryption angle of the quantum rotating door. This method combines the randomness of measured quantum with the chaotic system to obtain a truly random sequence. Using this random sequence can better Keep images confidential. Experimental results show that this method has high security and sensitivity to keys. In the sensitivity analysis of the results of the simulation experiment, its NPCR (Number of Pixels Change Rate) values floated around 99.60%. In the field of image encryption, the reliability of image encryption is greatly enhanced.
