Fast Image Encryption Method using S-Box and Hyperchaotic System

Abstract

Modern technology necessitates the transmission of millions of images between users daily. Securing these images is critical. Digital image encryption is a popular method for safeguarding image content. Chaos theory is a popular choice for image encryption due to its unpredictable and random nature. This paper proposes a cryptosystem based on the combination of  6D hyperchaotic and Chen for a more secure image encryption system; firstly, we get randomly generated variables produced by the six-dimension hyperchaotic system to confuse the original image. Secondly, bit XOR is used for more scrambling, and finally, the S-box is used for diffusion. It is dynamically generated by the Chen system with variable conditions. A novel chaotic S-box-based image encryption strategy has been developed to enhance the security and efficiency of image encryption systems ultimately. The security study and simulation results confirm the suggested scheme's effectiveness. Because of the new scheme's clear efficiency advantages and attacks, real-time image encryption may be used more effectively.
