Protecting Digital Images Using Keys Enhanced by 2D Chaotic Logistic Maps

This research paper presents a novel digital color image encryption approach that ensures high-level security while remaining simple and efficient. The proposed method utilizes composite key r x of 128-bits to create small in-dimension private (a chaotic map), which is then resized match the matrix dimension. uncomplicated can be applied any without modification. Image quality, sensitivity analysis, correlation quality speed attack robustness analysis are conducted prove efficiency aspects method. shows improves performance cryptography by minimizing encryption–decryption time maximizing throughput process cryptography. results demonstrate provides better than existing methods. Overall, this new highly secure, efficient, applicable various images.
