Analytic Study of a Novel Color Image Encryption Method Based on the Chaos System and Color Codes
Algorithm 1
(Pixel permutation).
Input. Color image I, secret key K1 = (ξ0, η), PWLCM (1)
Output. Image array with scrambled pixels
Step 1. One-dimensional array of size is created by reshaping the original image matrix to one-dimensional array, where are the number of rows and columns, respectively, of the original image matrix
Step 2. Using PWLCM (1) with the key, generate the chaotic sequence and sort the resulting sequence in ascending order
Step 3. Compute the position vector of in and note down the transformed positions
