Using Whale Optimization Algorithm and Chaotic Map to Encrypt Images

Developing innovative methods to protect data transmitted over the Internet and stop unauthorized access to it is one of the most important challenges researchers encounter. A new approach to image data encryption has been introduced in this research, which is based on the chaotic map and Whale Optimization Algorithm (WOA). The encryption algorithm, which is entitled IEBCWOA, consists mainly of two phases: The first phase deals with shuffling the pixel positions by employing two keys for column and row permutation, respectively, generated by the Zaslavskii map, while the second phase deals with choosing the optimal substitution key by employing WOA and Zaslavskii Map. Several experiments have been carried out, and the results are compared to those of other researchers. The test findings indicated a satisfactory safety rate when compared to other existing techniques.
