Zusammenfassung:The transmission of an excessive number of images between users via the Internet and other communication media necessitates the use of effective techniques to protect the images from unauthorized usage. Encryption is one of the most effective methods for protecting both images and data. This paper presents a new grayscale image encryption method that integrates a seven-dimensional hyperchaotic system with Pascal's matrix. The algorithm used the hyperchaotic system to first confuse the original image before diffusing the permuted image using Pascal's matrix. To assess the image encryption performance, the suggested algorithm used histogram, correlation coefficient, differential attack, information entropy, and noise attack. Simulation results indicate that the suggested algorithm has a high level of security and is resistant to a variety of attacks.
