transformed images into a DNA sequence format and hyper-image format for shuffling and replacement, and designed a chaotic pseudo-random number generator to participate in the above operations, subsequently achieving secure encryption. In the past decades, in order to meet security demands, researchers have proposed various technologies for image encryption. Specifically, images filled with plain-text information are reconstructed as noise-like data, making it difficult for attackers to recover the original data. Image encryption presents an effective pattern for people to send or receive information securely over a network safely. Thus, methods to secretly and securely transmit and store digital images, particularly those containing private information, has become a central issue among current research fields. With the development of scientific innovations and modern technologies such as the Internet, various forms of multimedia carriers have gradually emerged, among which digital images have seen wide usage in politics, economy, national defense, education, and other fields attributing to their advantages of visual visibility. Several simulation experiments present findings that the image encryption algorithm contains a high level of security, and can compete with other encryption algorithms. In addition, a new image encryption algorithm is designed based on these modified chaotic sequences, in which magic square theorem is incorporated to exchange pixel positions, and the octree principle is invoked to achieve pixel bit shifting. Then, through a number of simulation experiments, the results demonstrate that the two-dimensional chaotic map treated by this mode exhibits better chaotic characteristics, including a larger chaos range and higher complexity. In this paper, a scheme to integrate a one-dimensional Logistic map by perturbation parameters with a delayed coupling method and feedback control is proposed and further deepens the randomness by selectively shifting the position of the chaotic sequence. Thus, enhancing the properties of chaotic maps are beneficial to the improvement of chaos-based encryption algorithms. Digital chaotic maps have been widely used in the fields of cryptography owing to their dynamic characteristics, however, some unfavorable security properties arise when they operate on devices with limited precision.
