摘要

The study establishes a unique encryption technique; information is encrypted using the Ikeda map, and some Cellular Automata Rules 30 security and randomness are implemented to encrypt the image. The actual image is XORed with a key, generated with Cellular Automata Rule 30. The second XOR takes place with a chaotic key generated from the Ikeda map, and this combination generates an uneasy mix of a deterministic and chaotic image. The encrypted image is so well chaotic and deterministic that self-chosen XOR on this will produce a very strong, secure encrypted image. The algorithm was analyzed for its appropriateness through various metrics and came out with entropy-7.9991, MSE-103.25, PSNR-26.89 dB, UACI-33.86%, and NPCR became 99.61%. The results show strong randomness effectiveness, and hence, this algorithm is able to resist cryptanalysis efficiently. In addition, lower correlations in the encrypted image are said to indicate higher security levels. This approach is ideally suited to any application requiring high security in image encryption in terms of secure image transmission and storage.
