A proposed lightweight image encryption using ChaCha with hyperchaotic maps

Image encryption plays a pivotal rule in enhancing telecommunications media. Since Privacy is necessaryin our daily life in many areas, the personal image will be encrypted when it sent it over the Internet to therecipient to maintain privacy issue. In this paper, the image is encrypted using ChaCha symmetric streamcipher with Hyperchaotic Map. Due to the sensitivity characteristics of initial conditions, pseudorandomness chaotic maps and control parameters in chaotic, Hyperchaotic maps is use, higher security isobtained via using initial seed number, variance of parameters, and unpredictable direction of chaotic. Thesuggested lightweight image encryption has confirmed robustness contra brute force attacks by providing amassive key space. Furthermore, the suggested lightweight image encryption is eligible to defense fromstatistical cracking, insecurity of image based on criteria's histogram correlation and entropy.
