Creation of S-Box based One-Dimensional Chaotic Logistic Map: Colour Image Encryption Approach.

Image security is evolving as an outstanding platform to provide security in the digital world. The external features of the Internet have driven the transfer of digital images from one place to another. In the area of security, the improvement of encryption and decryption is crucial. Chaos-based encryption has recently been proposed as a reliable and effective solution for image security. The excellent properties of unpredictability, ergodicity, and sensitivity to their parameters and initial values have enabled the wide use of chaotic maps in security applications. This paper introduces a colour image encryption approach to secure colour images and constructs s-box relying on the onedimensional logistic map. The proposed colour image encryption approach relies on the generated new S-box. The new S-box passed the S-box test criteria for balanced, completeness, avalanche, and strict avalanche. Also, the encryption performance analysis metrics like information entropy, correlation analysis, histogram analysis, and differential attack are recorded. Based on the results, the values of information entropy, NPCR, and UACI for the Lena image reached are 7.9972, 99.601%, and 33.5647% respectively. [ABSTRACT FROM AUTHOR]
