Image Encryption Using Quadrant Level Permutation and Chaotic Double Diffusion
摘要
Information security is becoming more and more important as information technology advances. In the fields of telecommunication networks, diagnostic imaging, and multimedia applications, information security is crucial. The use of images as a medium for the conveyance of information is integral to the information age. However, image data differs from traditional text-based information in that it is dense and has strong pixel correlation. As a consequence, image encryption no longer works with traditional encryption techniques. Consequently, a safe and difficult-to-crack image encryption technique is required. In this research, a new symmetric image encryption technique based on improved Henon chaotic system with byte sequences and a unique method of shuffling a picture’s pixels is suggested. This algorithm produces effective and efficient encryption of images. The suggested image encryption technique created a new dimension for safe image transfer in the realm of digital transmission by causing more confusion and diffusion, according to statistical analysis and experimental key sensitivity analysis.
