Image encryption algorithm based on a memcapacitor‐based hyperchaotic system and DNA coding

Abstract

AbstractIn today's digitally connected world, the protection of privacy and data security in open communication media (OCM) is paramount. As digital devices become more widespread and increase in global connectivity, the significance of image encryption has reached unprecedented levels. Traditional encryption techniques often fall short when applied to images due to their unique properties such as high correlation and large data quantities. To address these challenges, this paper presents a novel image encryption method that integrates principles from deoxyribonucleic acid (DNA) rules, the logistic map, and a hyperchaotic model with memcapacitors. The intricate and unpredictable nature of the memcapacitor‐based hyperchaotic system, coupled with deficiencies in current image encryption algorithms, serves as a catalyst for the development of this new algorithm. The proposed encryption strategy leverages the encoding properties of DNA and the complex dynamics of hyperchaotic systems to achieve enhanced image encryption. Through simulations and evaluations using reference images, the effectiveness of the method is demonstrated. It surpasses current techniques in terms of statistical robustness, resistance to brute‐force attacks, and protection against differential attacks. The research concludes that combining DNA principles, logistic maps, and memcapacitor‐based hyperchaotic systems significantly improves image encryption. This approach enhances data security for image transmission in open communication channels, addressing the limitations of traditional encryption techniques. As digital connectivity expands globally, the demand for robust image encryption is expected to increase, making this research pivotal in establishing standards for future advancements in image encryption algorithms.
