Image Encryption Based on 5-Neighbor Programmable Cellular Automata

ABSTRACT

With the rapid development and spread of non-face-to-face digital technologies and services due to the spread of COVID-19, real-time non-face-to-face online meetings, education, telemedicine, online collaboration, telecommuting, various non-face-to-face tasks in the financial sector, and the sharing economy are frequent. As a result, network traffic increases and the demand for real-time security of multimedia is increasing. Security of information, including image content, is an essential part of today's communication technology and is very important for safe transmission. In this paper, we design a 5-neighbor programmable cellular automata (FNPCA) based ROI (region of interest) image encryption system that can effectively reduce computational cost and maintain an appropriate level of security. © 2022 IEEE.
