Effective Multiple Image Encryption Based on 3D Cubes & Hyperchromatic Map

Abstract

Effective Multiple Image Encryption Based on 3D Cubes and Hyperchromatic Map" offers a cutting-edge method for multiple image encryption that uses 3D cubes and a hyperchromatic map. map with hyperchromacy. The suggested approach attempts to improve the efficacy and security of picture encryption methods. In this method, photographs are separated into blocks and represented as 3D cubes, each comprising three orthogonal image planes. Giving each picture block a different color, a hyperchromatic map is created, which aids in maintaining the spatial association between the blocks during encryption. Several processes, such as block permutation, pixel bit-shuffling, and key-based mixing, are used throughout the encryption process. By introducing unpredictability and uncertainty, these techniques make it challenging for unauthorized users to decipher any useful information from the encrypted pictures. A key management strategy is utilized to increase security, using distinct keys for block permutation, pixel bit-shuffling, and key-based mixing. The keys are produced dynamically for each encryption session using information from the hyperchromatic map, making the encryption process very safe and resistant to assaults. Experimental findings show that the suggested strategy is effective regarding security, resilience, and efficiency. The encryption approach is appropriate for real-time applications that need safe transmission and storage of many pictures since it delivers good encryption quality while preserving a minimal computational overhead.
