Enhancing Image Encryption with Quadrant-Based Layered Multi-Key Systems

The exponential growth of technology poses significant challenges to the robustness of currentencryption methods, such as AES and DES, which may become vulnerable soon. This researchintroduces a novel approach, the Layered Multi-Key Encryption and Decryption System,designed to enhance the security and efficiency of image encryption. The proposed systememploys Quadrant-Based Keys, a unique technique that divides an image into quadrants andapplies distinct keys to each section, creating an additional layer of complexity. By focusing oncolor channels, this method ensures granular encryption, making unauthorized accessexceedingly difficult. Experimental results demonstrate that this system outperforms traditionalalgorithms in terms of speed and security. However, the requirement to save keys in a .mat fileposes a slight limitation, as these keys are essential for decryption. This research paves the wayfor next-generation encryption systems, offering a robust solution for secure image datatransmission and storage.
