Cryptographic Services Based on Cellular Automata in Image Encryption

Image encryption is vital for safeguarding sensitive visual data as it moves over different networks or gets stored in digital formats. Recently, cellular automata (CA) have emerged as promising tools for this task, thanks to their capability to produce intricate and chaotic patterns. This study introduces an encryption algorithm based on cellular automata rules 90 and 150. These rules are chosen for their distinct attributes in creating pseudo-random sequences, which serve for scrambling the pixel values of the input image. Experiments carried out on the results, including comparing histograms between the original and encrypted images, along with statistical analyses, illustrate the effectiveness and efficiency of the proposed encryption approach in ensuring security.
