Abstract
Internet use and other communications technologies like wireless networks, cloud computing, and the Internet of Things have skyrocketed in recent decades. This research seeks to provide a structured color picture encryption technique for wireless sensor networks (WSNs). The approach uses a 1-D exponential modified chaotic map (1-D EMC), 2-D discrete wavelet transform, and a 1-D modified version of the logistic map (1-D MVL) to reduce data and improve transmission, especially for images. The XOR operator and random permutation of image matrix rows and columns strengthen the technique against numerous attacks. Statistical analyses are performed on the proposed encryption technique, and the values of these statistical tests presented in the tables are satisfactory. A fair comparison with other competitive existing algorithms shows the effectiveness of the proposed encryption algorithm and can be opted for practical use.
